40. On the nature of beta-delayed neutron emission near 54Ca

Zhengyu Xu (1University of Tennessee, Knoxville)

Beta-delayed neutron emission (beta-n) plays an important role in diverse areas of nuclear science, from nuclear reactors to astrophysical nucleosynthesis. Due to its complicated nature, modeling the beta-n process relies on the validity of Bohr’s hypothesis of the compound nucleus (CN) [1]. Here, the decay of the excited nucleus, populated in beta decay, depends only on its spin, parity, and...

The existence of nuclear isomers offers crucial information for testing nuclear models and understanding shell evolution far from stability. Decay properties including half-lives and transition strengths associated with these isomeric states can be used to characterize them and serve as sensitive probes of their underlying structure.
