The conservation of the number of particles within the QRPA plays an important role in the evaluation muon capture rates in all light nuclei with A \precsim 30 . The violation of the CVC by the Coulomb field in this mass region is of minor importance

We perform a self-consistent relativistic QRPA (RQRPA) calculation of $2\nu\b\b$-decay based on relativistic BCS (RBCS) mean field theory results for odd-odd intermediate nuclei $^{48}$Sc, $^{76}$As, $^{82}$Br, $^{100}$Tc, $^{128}$I, and $^{130}$I. T

We compute one- and two-nucleon kinetic-energy spectra and opening-angle distributions for the nonmesonic weak decay of several hypernuclei, and compare our results with some recent data. The decaymics is described by transition potentials of the one

We evaluate the coincidence spectra in the nonmesonic weak decay (NMWD) $\Lambda N\go nN$ of $\Lambda$ hypernuclei $^{4}_\Lambda$He, $^{5}_\Lambda$He, $^{12}_\Lambda$C, $^{16}_\Lambda$O, and $^{28}_\Lambda$Si, as a function of the sum of kinetic ener

We derive general explicit expressions for a shell-model calculation of the intrinsic asymmetry parameter, $a_\Lambda$, in nonmesonic weak hypernuclear decay. They include the effects of three-body kinematics in the final states of the decay and corr

A novel comparison between the data and the theory is proposed for the nonmesonic (NM) weak decay of hypernuclei. Instead of confronting the primary decay rates, as is usually done, we focus our attention on the effective decay rates that are straigh

We extend the formalism of weak interaction processes, obtaining newexpressions for the transition rates, which greatly facilitate numerical calculations, for both neutrino- nucleus reactions and muon capture. Explicit violation of the conserved vect

To comprehend the recent Brookhaven National Laboratory experiment E788 on He Λ 4, we have outlined a simple theoretical framework, based on the independent-particle shell model, for the one-nucleon-induced nonmesonic weak decay spectra. Basically,

We report the preliminary result of an exact calculation of the asymmetry parameter, aΛ, in the nonmesonic hypernuclear decay, based on a one-meson-exchange (OME) model. For the case of Λ 5He and including one-pion-exchange only, the result is show
