摘要：
High-spin states in 183Pt have been studied for the first time using the reactions 154Sm(34S, 5n) and 170Yb(16O,3n). Rotational bands built on the Nilsson configurations 1 2-[521], 7 2-[514] and 9 2+[624] were observed up to spin values of 39 2- 49 2 h {combining short stroke overlay}. Quasiparticle alignments and band crossing frequencies were investigated in these bands. A large signature splitting was observed in the νi 13 2-band structure. The experimental results were compared with total routhian surface calculations, in which the shape of the nucleus could be followed as a function of rotational frequency for different quasiparticle configurations. © 1990.
