α-cluster structure in 62,64Ge described by the local potential approach

The unstable nuclei 62Ge and 64Ge are analyzed in terms of the α + core structure applying a nuclear potential with (1 + Gaussian)×(W.S. + W.S.3) shape. The ground state bands of 62Ge and 64Ge and first negative parity band of 64Ge are calculated and compared with experimental data. The calculated 64Ge ground state band gives a good account of the experimental energies from 0+ to 8+ state. The rms intercluster separations and B(E2) transition rates are obtained for the 64Ge ground state band and a discussion is presented.
