Abstract | The angular momentum projected shell model(PSM) is applied to the nucleus Rb-84. The results of theoretical calculations about the positive-parity yrast band with configuration pig(9/2)circle timesvg(9/2) and the negative-parity yrast band with configuration pi(P-3/2, f(5/2))circle timesvg(9/2) are compared with experimental data; especially, the mechanism of signature inversion in the positive-parity yrast hand is discussed. The interpretation within the PSM shows that this signature pattern is a signal of a substantial quadrupole shape change with increasing spin,where the nucleus evolves from a prolate shape at low spins through a triaxial shape to an oblate shape at high spins. In addition,the nuclear shape for these two bands are also specified. |
