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.

Weak interaction processes continue to be hot topics in fundamental physics research. In this paper, we briefly review some recent advances in the theoretical study of beta and double-beta decays that include both the nuclear and atomic part of these processes. On the nuclear side, we present a statistical approach for the computation of the nuclear matrix elements (NME) for neutrinoless double-beta (0νββ). A range of NME values, the most probable value for NME, and the associated theoretical uncertainty are given. Correlations with other related observables are shown as well. On the atomic si

When excited by a beam of runaway electrons, a lower luminescence intensity is observed. Also in some cases a delay in the appearance of luminescence relative to the onset of the electron beam action was found. The

Based on measuring of double and triple coincidences between γ-quanta, conversion electrons (СЕ) and β-particles with electrons (including the eo-electrons of secondary electron emission - coincidence (γ, CE)-(e, eo) and coincidence γβео) the output of eo-electrons is measured for β-decays of 152,154Eu for different components of the β-spectrum. In the β-decay is established that β-particles and shake-off electrons (observed by eo-electrons), which are caused by them are correlated in the direction of emission, demonstrating predominantly emitting to the same half sphere.

Abstract:

The probabilities of the formation of final ions produced by the cascade decays of vacancies in the K, L, M, N, and O shells of the gold atom are calculated. Simulation of the cascade decays of vacancies is performed by direct construction and analysis of decay trees using branching ratios and transition energies calculated in the Pauli–Fock approximation for multivacancy electron configurations arising in the course of the cascade decay. Accounting for additional monopole ejections of electrons (shake-off) accompanying the cascade transitions leads to a slight increase in the average charges

Abstract:

The mean life of the free neutron is about fifteen minutes, after which it decays into a proton plus an electron and an electron-neutrino. According to the Planck vacuum (PV) theory, however, it is the neutron and ``antineutron" meta-particles (MP)s that decay, in roughly fifteen minutes, into the stable electron and proton cores. The electron and proton core spins remain constant during the transformations-so there is no need for the neutrino spin correction during the decay process, bringing into question the validity of the neutrino itself.

For electrons with small excess energy (< 50 meV), the strong increase in the ΔR decay rate with decreasing excitation density suggests that screening of the Coulomb interaction may play an important role in the processes

Abstract A neutron star harbors 𝒪(1056) electrons in its core, and almost the same number of muons, with muon decay prohibited by Pauli blocking. However, as macroscopic properties of the star such as its mass, rotational velocity, or magnetic field evolve over time, the equilibrium lepton abundances (dictated by the weak interactions) change as well. Scenarios where this can happen include spin-down, accretion, magnetic field decay, and tidal deformation. We discuss the mechanisms by which a star disrupted in one of these ways re-establishes lepton chemical equilibrium. In most cases, the dom

Using a hydrodynamical model of the plasma, the nonlinear dispersion relation and growth rate are obtained.

Abstract:

A combined interpretation of the Calorimetric Electron Telescope (CALET) [Formula: see text] spectrum up to 3[Formula: see text]TeV and the AMS-02 positron spectrum up to 500[Formula: see text]GeV was performed and the results are discussed. To parametrize the background electron flux, we assume a smoothly broken power-law spectrum with an exponential cutoff for electrons and fit this parametrization to the measurements, with either a pulsar or 3-body decay of fermionic Dark Matter (DM) as the extra electron–positron pair source responsible for the positron excess. We found that depending on t

Abstract:

In this paper, we update the phase-space factors for all two-neutrino double electron capture processes. The Dirac–Hartree–Fock–Slater self-consistent method is employed to describe the bound states of captured electrons, enabling a more realistic treatment of atomic screening and more precise binding energies of the captured electrons compared to previous investigations. Additionally, we consider all s-wave electrons available for capture, expanding beyond the K and L1 orbitals considered in prior studies. For light atoms, the increase associated with additional captures compensates for the d

Abstract:

We study the quasimode decay of a lower-hybrid wave and a damped ion cyclotron wave in a plasma having two kinds of electrons. This decay channel is also investigated for a cylindrical plasma. The behaviour of the threshold and growth rate with variations in Tn/Tc and non/noc are studied, and a comparison is made with previous results. Our results show that the growth rate and the threshold for the onset of parametric decay are influenced by the presence of the second electron species.

Full text

Abstract:

A large number of studies have examined the origins of high-catalytic activities of nanoparticles, but very few have discussed the lifetime of high-energy electrons in nanoparticles. The lifetime is one of the factors determining electron transfer and thus catalytic activity. Much of the lifetime of electrons reported in the literature is too short for a high transfer-efficiency of photo-excited electrons from a catalyst to the attached molecules. We observed TiO2 nanoparticles using the femtosecond laser two-color pump-probe technique with photoemission electron microscopy having a 40 nm spat

Abstract:

In most negative hydrogen ion sources, an external magnet is installed near the extraction region to reduce the electron temperature. In this paper, the self-developed CHIPIC code is used to simulate the mechanism of a magnetic filter system, in the expansion region of the negative hydrogen ion source, on “hot” electrons. The reflection and the filtering processes of “hot” electrons are analyzed in depth and the energy distribution of electrons on the extraction surface is calculated. Moreover, the effects of different collision types on the density distribution of “cold” electrons along the X

Abstract:

The Tv2a center in 4H-SiC irradiated by electrons at room temperature has been studied by pulsed EPR. Various techniques such as pulsed ELDOR (electron-electron double resonance), 2-pulse echo decay, 3-pulse inversion recovery, pulsed ENDOR (electron nuclear double resonance), and 3-pulse ESEEM (electron spin echo envelope modulation) have been applied to perform the detailed structure determination and to exploit applicability for the coherent spin control experiments.

Abstract:

The processes of photon creation or atom ionization during annihilation of positron with other electron of daughter’s atom at β+-decay are considered. The estimations for the probability of one photon annihilation emitted in the process β+-decay of positron with K-electron of daughter’s atom are obtained. Process of atomic shell ionization during annihilation of positron, emitted at β+-decay, with K-electron of daughter’s atom is considered. Ratio of probabilities of these processes to the probability of ordinary β+-decay is found.
