The 180<A<190 Hf-Ta-W region near the valley of stability display robust axially symmetric prolate deformation and associated high-K isomerism. Mapping the evolution of shapes in approaching the Z=82 and N=126 shell closure from the very deformed rare-earth mid-shell region is of great interest for honing nuclear structure models, with a loss in axial symmetry and a transition from prolate to...
Beta-delayed neutron emission (βn) is the prevalent decay mode in very neutron-rich nu- clei that are involved in the nucleosynthesis via rapid (r-) neutron capture process [1]. Characterized as a two-step decay mechanism, it involves β-decay feeding into excited states beyond the neutron separation energy in the daughter nucleus, succeeded by neu- tron emission, resulting in a lower-mass...
Anomalies in the systematics of nuclear properties challenge our understanding of the underlying nuclear structure. One such anomaly emerges in the Zr isotopic chain as a dramatic ground- state shape change, abruptly shifting from spherical into a deformed one at N=60. Only a few state-of-the-art theoretical models have successfully reproduced this deformation onset in 100Zr and helped to...
