Transition strengths and signature inversion in odd-odd 'ANTPOT. 74 Br'

Lifetimes of states in ${}^{74}\mathrm{Br}$ produced by the ${}^{60}\mathrm{Ni}{(}^{16}\mathrm{O},np)$ reaction at 50 MeV have been measured by using the recoil-distance method. From these experiments several reduced transition strengths for the low energy states have also been determined. The results show that the alternating pattern in the $B(M1)$ strengths of the yrast positive parity band is preserved across the signature inversion region.
