Shape changes in neutron rich $N =$\textit{ 43} isotones

\textit{et al.} Nuclei in the transitional region with \textit{28 \textless Z \textless 50} and \textit{40 \textless N \textless 50} are very sensitive to shape changes with addition of individual nucleons due to close-lying neutron orbitals in the \textit{fpg} model space. A systematic comparison of the structure of $N =$\textit{ 43} isotones, focussing on new results on $^{\mathrm{75}}$Ge and $^{\mathrm{73}}$Zn will be presented. Both nuclei were populated in deep inelastic scattering reactions, $^{\mathrm{76}}$Ge $+ \quad^{\mathrm{208}}$Pb and $^{\mathrm{76}}$Ge $+ \quad^{\mathrm{238}}$U, at \textasciitilde 25{\%} above the Coulomb barrier, using Gammasphere and ATLAS facility at ANL. A number of new transitions and levels have been identified in both nuclei. The experimental results and their comparison to the theoretical calculations will be presented.
