A systematic study of the β-decay neutron-deficient nuclei has been carried out and provided spectroscopic information importance for both nuclear structure astrophysics. Following an overview most relevant achievements, we focus on latest results β decay 60 Ge 62 Ge. We also summarise our mass excesses in comparison with systematics a recent measurement. Finally, present updated half-life tren...

Core collapse of massive stars and binary neutron stars or black hole-neutron star binary mergers are likely progenitors of long and short duration gamma-ray bursts respectively. Neu-tronized material in the former and neutron star material in the latter are ejected by the central engine implying a neutron-rich jet outflow. A free neutron, however, beta decays to a proton, an electron (beta) an...

In neutron star mergers, excess nuclei and the r-process are important factors governing production of heavier nuclear systems. A single-particle model evaluation silicon suggests that heaviest Z = 14 nucleus will have mass 54 with filling 1f5/2 shell. 43 – isotopes limited experimental half-life data, but predicts beta decay half-lives in range 0.442 8.06 ms. Based on previous calculations for...
