The influence of nucleon-nucleon short-ranged correlations (SRC) on nuclear superallowed
β decay is examined. The need for this is driven by the observed depletion of spectroscopic …

In this work we report on the effects of short-range correlations upon the matrix elements of
neutrinoless double beta decay (0νββ). We focus on the calculation of the matrix elements of …

Recent experiments make possible the approximate determination of mixing ratios∫ σ/∫ 1
for several nuclei in J→ J beta transitions. We verify that the signs of these ratios in two …

A self-consistent calculation of nuclear matrix elements of the neutrinoless double-beta
decays (0 ν β β) of Ge 76, Se 82, Zr 96, Mo 100, Cd 116, Te 128, Te 130, and Xe 136 is …

Measurements of the β− γ (CP) correlation have been made for the 3 2−(β+, 0.84 MeV) 3
2−(γ, 1.38 MeV) 7 2−(ground-state) cascade in the decay of 57Ni and for the 5 2−(β−, 1.02 …

The energy dependance of the 437-keV β—176-keV γ directional correlation is measured
with a conventional slow-fast scintillation assembly. The results are in good agreement with …

The non-mesonic weak decay of Λ-hypernuclei is studied within a microscopic diagrammatic
approach which includes, for the first time, the effect or the Δ-baryon resonance. We adopt a …

We study the nonmesonic weak decay (NMWD) ΛN→ nN of hypernucleus induced by one
nucleon N= n, p. The whole process is described by two coupled models: one for the primary …

The nuclear matrix elements for two-neutrino double-β and zero-neutrino double-β decay of
Ge 76 are evaluated in terms of the configuration-interaction (CI), quasiparticle random …

A method to calculate the nuclear double beta decay (2 ν β β and 0 ν β β) amplitudes within
the continuum quasiparticle random phase approximation (cQRPA) is formulated …
