Low spin structure of odd-odd N = Z nuclei Co-54 and Mn-50

The Data on low spin states in the two odd-odd nuclei Co-54 and Mn-50 investigated with the Fe-54(p,ngamma)Co-54 and Cr-50(p,ngamma)Mn-50 fusion evaporation reactions at the FN-TANDEM accelerator in Cologne are reported. The states of quasideuteron character are identified from the strong isovector M1 transitions by comparison to a full pf-shell model calculation and experimental values of branching ratios for the low-lying states.
