Signature splitting and shape coexistence at high spin in the neutron deficient nucleus ~(129)Nd are investigatedwith the configuration-dependent cranked Nilsson-Strutinsky approach.The calculated bands are compared with theobserved signature partner bands and very good agreement results at high spin are obtained.The observed deformedbands are confirmed as normal and highly deformed and their properties are explained theoretically.Terminating statesin ~(129)Nd and other terminations axe 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 intermediateprincipal axis in several interesting configurations of ~(129)Nd are discussed.The experimental results for ~(131)Nd are simplydiscussed and the calculated bands are in good agreement with observed bands at high spin.Triaxial shapes in ~(127)Ndwith a triaxial deformation of γ～-12° are predicted and should be observed experimentally.The value of negativeγ of π(h_(11/2))~4v(h_(11/2))~7 configuration increases with neutron number increasing in ~(127,129,131)Nd.The triaxial shapeevolutions with neutron number increasing in ~(127,129,131)Nd and in ~(126,128,130,132)pr are explained by the strong drivingforce of specified single particle orbitals towards to triaxial shape.
Signature splitting and shape coexistence at high spin in the neutron deficient nucleus ~ (129) Nd are investigated with the configuration-dependent cranked Nilsson-Strutinsky approach. The calculated bands are compared with theobserved signature partner bands and very good agreement results at high spin are The observed deformed bands are confirmed as normal and highly deformed and their properties are covered theoretically. Debugging states in ~ (129) Nd and other terminations ax 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 intermediateprincipal axis in several interesting configurations of ~ (129) Nd are discussed. The experimental results for ~ (131) Nd are simply discarded and the calculated bands are in good agreement with observed bands at high spin .Triaxial shapes in ~ (127) Ndwith a triaxial deformation of γ ~ -12 ° are predicted and should be observed d experimentally. The value of negativeγ of π (h_ (11/2)) ~ 4v (h_ (11/2)) ~ 7 configuration increases with neutron number increasing in ~ (127,129,131) Nd.The triaxial shape evolutions with neutron number increasing in ~ (127,129,131) Nd and in ~ (126,128,130,132) pr are explained by the strong driving force of specified single particle orbitals towards to triaxial shape.
