Abstract
High-spin states in the doubly odd $N=75$ nuclei ${}^{136}\mathrm{Pm}$ and ${}^{138}\mathrm{Eu}$ were populated following the ${}^{116}\mathrm{Sn}{(}^{24}\mathrm{Mg},p3n)$ and ${}^{106}\mathrm{Cd}{(}^{35}\mathrm{Cl},2pn)$ reactions, respectively. A new $\ensuremath{\Delta}I=1$ band is reported in ${}^{138}\mathrm{Eu}$ and new data are presented for the recently reported band in ${}^{136}\mathrm{Pm}.$ Polarization and angular correlation measurements have been performed to establish the relative spin and parity assignments for these bands. Both bands have been assigned the same $\ensuremath{\pi}{h}_{11/2}\ensuremath{\bigotimes}\ensuremath{\nu}{h}_{11/2}$ structure as the yrast band and are suggested as candidates for chiral twin bands.
