| 英文摘要 | Stable octupole deformation was predicted and subsequently found to occur centered around the reinforcing shell gaps at Z = 56 and N = 88 for beta (3) similar or equal to 0.15 Evidence for stable octupole deformation is reviewed. New results in Ba-145 and Ba-141 are presented. Rotational enhancement of octupole deformation is found at intermittent spills ill Ba and La nuclei and the quenching of such deformation at higher spins in Ba-146 but not in Ba-144. Symmetric and asymmetric shapes coexist in Ba-145 and La-145. Evidence for octupole correlation is found in Pr-147 but only h(11/2) bands are found in Pr-149,Pr-151. The new Ba-141 levels have two sets of two intertwined bands of levels with the characteristics of octupole deformation as found in Ba-143,Ba-145, however, a problem occurs with the assignment of parities in Ba-141. |
