摘要：

The low-lying collective bands of positive parity states in (fp) shell nuclei are described in the deformed Hartree-Fock method by projecting states of definite angular momenta from 'the lowest energy intrinsic states in (sd)-1 (fp) n+1 configurations. The modified Kuo-Brown effective interaction for (fp) shell and modified surface delta interaction (MSDI) for a hole in (sd) shell with a particle in (fp) shell have been used. The collective bands of states are in general well reproduced by the effective interactions. The excitation energies of the band head states are however off by about one MeV. The calculated magnetic moments of the band head j=3/2+ states are in reasonable agreement with experiment. Using effective charges e p=1.33 e and e n=0.64 e we get fairly good agreement for E(2) transitions. The hindered M(1) transition strengths are reproduced to the correct order however they are slightly higher compared to experiment. © 1977 the Indian Academy of Sciences.
