Abstract

Excited states in $^57Mn$ are populated using the $^55Mn(^18O$, $^16O)^57Mn$ two-neutron transfer reaction at the FN tandem accelerator in Cologne. Lifetimes of excited nuclear states in $^57Mn$ were determined utilizing the Doppler-shift attenuation method. A comparison between experiment and shell-model theory was made for excitation energies and reduced transition strengths along the odd-$Z$ isotopes Sc, V, Mn, and Co. The new results on transition strengths in $^57Mn$ are described well by the standard interactions GXPF1A and KB3G. The development along the $N=32$ isotones for these odd-$Z$ nuclei and discrepancies between experiment and theory are discussed.
