Shell-model calculation of ¹⁰⁰Mo double -β decay

NUCLEAR STRUCTURE ¹⁰⁰Mo; calculated neutron effective single-particle, proton and neutron single-particle energy spacings, running sum of B(GT) strength up to 3 MeV. ¹⁰⁰Mo, ¹⁰⁰Ru; calculated levels, J, π, B(E2). Effective shell-model Hamiltonian with realistic nucleon-nucleon potential. Comparison to experimental data.

RADIOACTIVITY ¹⁰⁰Mo(2β^-); calculated nuclear matrix elements for double β-decay and neutrinoless double β-decay to yrare and yrast 0⁺ states in ¹⁰⁰Ru. Effective shell-model Hamiltonian with realistic nucleon-nucleon potential and decay operators derived within the many-body perturbation theory. Comparison to available experimental data and other theoretical predictions.

Role of low-lying resonances for the ¹⁰Be(p, α)⁷Li reaction rate and implications for the formation of the Solar System

NUCLEAR REACTIONS ¹⁰Be(p, α), (α, n), E not given; ¹⁰Be(ν, e^-), E=2.8-10 MeV; analyzed reaction rates, σ; deduced influence on the content of ¹⁰Be in supernovae environment. ¹⁰Be(p, α), E<1.5 MeV; analyzed reaction rate, experimental data on resonance in ¹¹B at 193 keV, ; deduced reaction rate, astrophysical S-factor. Showed that, with the new reaction rate, a low-mass corecollapse supernovae is unlikely to produce enough ¹⁰Be to explain the observed ¹⁰Be/⁹Be ratio in meteorites. Comparison to data from JINA-REACLIB.
