摘要：

The high-spin structure of 129Ba was investigated via in-beam gamma-ray spectroscopy allowing many new transitions to be placed in the level scheme. Two isomeric states with lifetimes of tau = 23 (2) ns (182 keV level) and 68 (2) ns (2463 keV level) were identified. A high-K 3-quasineutron configuration [7/2+[404]x7/2-[523]x9/2-[514]] is proposed for the latter. A discussion of the high-spin structure and the deformation driving effects in 129Ba is presented in terms of the cranked shell model. The conclusion reached is that the alignment gains are dominated by h11/2 proton pairs,
