Structure of Neutron-rich Nuclei Beyond $N=50$

Abstract

The measurement of the $\beta$-decay scheme of $^{85}$Ga triggered questions on the properties of the low-lying states in $^{85}$Ge. In order to inspect the sensitivity of the results to the neutron $d_{5/2}$ and $s_{1/2}$ single-particle states, we performed an analysis of the level structure in the $N=51$ $^{83}$Ge and $N=53$ $^{85}$Ge isotopes.
