Abstract:
The electron spin decoherence in endohedral fullerene A@C 60 is studied at low temperature using master equation under the Markov approximation. At lower magnetic field the polarization decay occurs with form e-(t/T1)2 consitent with previous reports having decays of the order of ℏ/A, and the relationship [Formula: see text] is satisfied. For the case of A@C 60 (A = N,P ) endohedral fullerenes, the decay times on the order of tens of ns are calculated. For a strong external magnetic field, polarization strongly depends on the external magnetic field, the decay time is suppressed.

Abstract:
In view of the recent interest in the decays of mesons into a pair of light leptons, a computation of the QED radiative corrections to the decay of π0 into an electron-positron pair is presented here. The analysis is based on the soft-photon resummation method, which, unlike first-order perturbation theory, allows for very strict invariant-mass cuts on the final electrons. When combined with the theoretical estimates for the non-radiatively corrected decay rate, the results of the present paper could help to determine if new physics affect this decay.

Abstract:
The Standard Model has been very successful in describing existing experimental data in nuclear and particle physics, but it still depends on numerous experiments for the determination of several important properties. For example, the assumption that only Vector(V) and Axial-Vector(A) interactions are present out of five possible types of weak interactions: V, A, Scalar(S), Pseudoscalar(P) and Tensor(T) is based on experimental results. The ion trap is an promising way for precise measurement of the beta-neutrinoangular correlation parameter "a" in beta decay. The unperturbed observation of the recoiled nucleus and electron allows reconstruction of the full decay kinematics. The goal of the BPT (Beta-decay Paul Trap) project is to measure "a" in the decay of 8Li. A deviation from the predicted value a =―1/3 would be an indication of a tensor contribution. 8Li was produced at the Argonne National Laboratory and about 20,000 events were recorded. By measuring the energy shift of the alpha particles in the 8Li decay, "a" is determined to be a =―0.329±0.009. This measurement is consistent with the Standard Model prediction. Upgrade of the system for a higher precision measurement is discussed.
Le Modèle Standard a connu un très grand succès pour décrire les mesures expérimentales autant en physique nucléaire qu'en physique des particules. Cependant, plusieurs expériences tentent toujours de vérifier certaines de ses hypothèses de base. Par exemple, c'est grace à des résultats expérimentaux, que l'on sait que seules les interactions de type Vecteur (V) et Axial-Vecteur (A) sont présentes dans le Modèle Standard, bien qu'il y a théoriquement trois autres types d'interactions faibles possibles : Scalaire (S), Pseudoscalaire (P) et Tenseur (T). Les pièges d'ions sont une avenue prometteuse pour mesurer précisément le paramètre de correlation angulaire bêta-neutrino, "a", des désintégrations bêta. L'observation du noyau de recul et de l'électron en l'absence de perturbations externes permet la reconstruction de la cinématique complète des désintégrations. Le but du projet BPT (Beta-decay Paul Trap) est de mesurer "a" à partir de désintégrations d'ions 8Li. Toute déviation des mesures par rapport à la valeur théorique a = ―1/3 serait une indication d'une contribution d'interactions de type Tenseur. Des ions 8Li ont été produits au Argonne National Laboratory, où prês de 20 000 événements ont été enregistrés. En mesurant le décalage énergétique des particules alpha originant de désintégrations 8Li, une valeur de a =―0.329±0.009 a été déterminée pour le paramètre de corrélation angulaire. Cette valeur est en accord avec la prédiction du Modèle Standard. Une amélioration du dispositif pour permettre des mesures de plus grande précision est discutée.

Full text
Abstract:
A sensitive search has been carried out for the rare decay $\rm K\sb{L}\to\mu e$. This decay violates conservation of separate lepton-number and thus is forbidden in the Standard Model of electro-weak interactions. Many new models have been proposed which could permit this process. The data were collected in the B5 beamline of the Alternating Gradient Synchrotron facility at the Brookhaven National Laboratory during the Spring, 1988 slow-extracted beam running period. The experiment was sensitive to approximately fifty million $\rm K\sb{L}\to\pi\pi$ decays. No $\rm K\sb{L}\to\mu e$ candidate events were detected. The 90% confidence level upper limit for the branching ratio is $\rm B(K\sb{L}\to\mu e) < 2.2 \times 10\sp{-10}$. This limit places a constraint on the mass of exotic particles proposed in many new theories.

Abstract:
Brookhaven National Laboratory AGS Experiment 871 (E871) has carried out a search for the very rare, GIM and helicity suppressed decay of the long-lived neutral kaon into an electron-positron pair. This decay is predicted within the Standard Model to occur with a branching ratio of {dollar}(9.0 \pm 0.4)\times 10\sp{lcub}-12{rcub}.{dollar} Data were taken during the 1995 and 1996 AGS HEP running periods on the B5 beamline. A signal of (4 {dollar}\pm{dollar} 2) {dollar}K\sbsp{lcub}L{rcub}{lcub}0{rcub} \to e\sp+e\sp-{dollar} events is seen with a physics background expectation of 0.2 events. The ratio of the partial decay widths {dollar}\Gamma(K\sbsp{lcub}L{rcub}{lcub}0{rcub} \to e\sp+e\sp-)/\Gamma(K\sbsp{lcub}L{rcub}{lcub}0{rcub}\to\mu\sp+\mu\sp-){dollar} is determined to be {dollar}(1.3\sbsp{lcub}-0.6{rcub}{lcub}+0.8{rcub} \pm 0.2)\times 10\sp{lcub}-3{rcub}.{dollar} Using the Particle Data Group value for the branching fraction of {dollar}K\sbsp{lcub}L{rcub}{lcub}0{rcub}\to\mu\sp+\mu\sp-{dollar} this corresponds to a branching fraction of {dollar}B(K\sbsp{lcub}L{rcub}{lcub}0{rcub}\to e\sp+e\sp-) = (9.4\sbsp{lcub}-4.6{rcub}{lcub}+5.9{rcub}) \times 10\sp{lcub}-12{rcub}.{dollar} This result represents the lowest branching fraction ever measured in particle physics.

Abstract:
Excited states in the transitional nucleus 160Yb have been studied using gamma-ray and conversion electron spectroscopy following the beta+/EC decay of 160Lu. Excited states in the nuclei 160Tm and 160Er have been studied following the beta+/EC decay of 160Yb and 160Tm, respectively. The data for the present study were obtained at TRIUMF in Vancouver, Canada at the ISAC-1 facility through radioactive sources moved into the combination of the 8pi gamma-ray spectrometer array and the Pentagonal Array for Conversion Electron Spectroscopy (PACES). Analysis of gamma-ray gated gamma-ray, gamma-ray gated conversion electron and conversion electron gated gamma-ray spectra resulted in the discovery of a new first excited state and the establishment of a level scheme for 160Tm which differs from the one adopted; as well as a test of the rotational characteristics of 160Er with intensity comparisons to both the spin-5 beta-decaying isomer study of by Singh et al. and the spin-parity 1- beta decay study of by Strusny et al. and Bykov et al.

Abstract:
Dynamics of electrons in solids is important to many phenomena such as optical, electrical, magnetical, and chemical properties of matter. Direct measurements of electron-electron (e-e) scattering rates provide critical tests for many body theories. Recent developments in ultrafast laser technology make it possible to probe directly femtosecond phenomena such as e-e scattering in metals. As a consequence of a large cross section for electron scattering hot-electon lifetimes in metals are in femtosecond regime, and until recently the scattering rate could only be evaluated by indirect measurements of heat and electrical transport properties. Two-photon time-resolved photoemission (TPTRP) measures the direct change of hot-electron population as a function of time. So far, this technique has been applied to direct measurement of electron relaxation by electron-phonon scattering in polycrystalline Au[1], hot electron thermalization by e-e scattering in Cu(100)[2], and image potential state decay on Ag(100) and Ag(111) surfaces[3]. With higher time resolution(<10fs) we have been able to resolve coherent component in hot-electron decay due to optical dephasing from the slower population decay rates of hot-electrons at Cu(100) and Cu(110) surfaces[4]. Here we report the results on Cu(100), Cu(110) and Cu(111) surfaces and compare them with Fermi liquid theory.

Abstract:
We investigated the effect of an intense dressing field on the energies of electrons ejected in an Auger process by means of electron spectroscopy. An amplified Ti:S laser provides infrared (800 nm) pulses of 40 mJ ranging from 150 femtoseconds to 8 picoseconds.[1] Part of the infrared beam is focused onto a liquid metal (gallium) target to produce broadband X-radiation. Auger electrons resulting from the X-induced LMM transition in argon[2] are detected in a time-of-flight electron spectrometer. When the X-ray beam and the infrared dressing beam overlap in space and time, sidebands appear around the Auger peaks, corresponding to absorption or emission of photons from the dressing field.

Abstract:
The tunneling time for electrons to escape from the lowest quasi-bound state in the quantum wells of GaAs/AlAs/GaAs/AlAs/GaAs double-barrier heterostructures with barriers between 16 Å and 62 Å has been measured at 80 K using photoluminescence excitation correlation spectroscopy. The decay time for samples with barrier thicknesses from 16 Å (≈ 12 ps) to 34 Å (≈ 800 ps) depends exponentially on barrier thickness, in good agreement with calculations of electron tunneling time derived from the energy width of the resonance. Electron and heavy-hole carrier densities are observed to decay at the same rate, in contrast to resonance-width calculations that indicate that heavy-hole tunneling times should be much longer than those for electrons. Reasons for this observation are discussed. Similar measurements in biased structures showing negative differential resistance are described.

Abstract:
We report direct measurements of the dynamics of photoinduced electrons at the liquid-solid interface of aqueous CdS colloids on the femtosecond time scale. Surface electron trapping was found to occur in < 100 fs, followed by rapid decay of the trapped electrons through primarily electron-hole recombination.

Abstract:
If a metal is excited by laser pulses for which the pulse duration is less than or comparable to the hot electron energy loss lifetime (τe), a transient inequality between the effective electron and lattice temperatures (Te and Tℓ, respectively) occurs [1]. Previous femtosecond thermotransmissivity [2] (thermoreflectivity [3,4]) of Cu (Au) have successfully been used to temporally resolve the decay of the hot electrons. These experiments relied on the fact that changes in the occupancy of electronic states near the Fermi level modulates the optical properties of the metal [5]. Although results for τe showed agreement with a calculation of electron-phonon coupling [6], there remains unresolved the role of lattice imperfections on hot electron energy loss and transport.
