英文摘要Signature splitting and shape coexistence at high spin in the neutron deficient nucleus Nd-129 are investigated with the configuration-dependent cranked Nilsson-Strutinsky approach. The calculated bands are compared with the observed signature partner bands and very good agreement results at high spin are obtained. The observed deformed bands are confirmed as normal and highly deformed and their properties are explained theoretically. Terminating states in Nd-129 and other terminations are predicted. There is shape coexistence within the same configuration from low-spin states to high-spin states. Possible normal and highly deformed bands with rotation around the intermediate principal axis in several interesting configurations of Nd-129 are discussed. The experimental results for Nd-131 are simply discussed and the calculated bands are in good agreement with observed bands at high spin. Triaxial shapes in Nd-127 with a triaxial deformation of gamma similar to-12 degrees are predicted and should be observed experimentally. The value of negative gamma of pi (h(11/2))(4) v (h(11/2))(7) configuration increases with neutron number increasing in Nd-127,Nd-129,Nd-131. The triaxial shape evolutions with neutron number increasing in Nd-127,Nd-129,Nd-131 and in Pr-126,Pr-128,Pr-130,Pr-132 are explained by the strong driving force of specified single particle orbitals towards to triaxial shape.
