Abstract :
High-spin states have been investigated in the A=47 mirror pair 4723V24 and 4724Cr23. The Coulomb energy difference (CED) between the two nuclei has been examined up to the band-terminating state of Jπ=312− and compared with that of their cross-conjugate nuclei, the mirror pair 4924Cr25 and 4925Mn24. The CED results are interpreted in terms of band-crossing and band-termination phenomena. A comparison of the cross-conjugate pairs indicates for the first time that the CED can reflect the changing nuclear deformation as a function of spin. CED calculations from full pf-shell calculations are presented for the first time and are shown to be in good quantitative agreement with the data.
