TL;DR
This paper investigates the beta decay and isomeric properties of neutron-rich nuclei near calcium-52 to understand the robustness of the N=32 sub-shell closure.
Contribution
It provides new experimental data on beta decay and isomeric states of specific neutron-rich isotopes near $^{52}$Ca, assessing the N=32 shell closure.
Findings
Evidence supporting the N=32 sub-shell closure
Measured beta-decay half-lives of $^{54}$Sc, $^{50}$K, and $^{53}$Ca
Implications for nuclear structure models near $^{52}$Ca
Abstract
The -decay and isomeric properties of Sc, K and Ca are presented, and their implications with respect to the goodness of the N=32 sub-shell closure discussed.
