rotational ground state band up to the state J π= 11+ at 6.994 MeV excitation energy. The
experimental Coulomb energy differences, obtained by comparison with the isobaric analog
states in its mirror 50 Cr, confirm the qualitative interpretation of the backbending patterns in
terms of successive alignments of proton and neutron pairs. A quantitative agreement with
experiment has been achieved by exact shell model calculations, incorporating the …
