| 英文摘要 | The properties of gamma instability in rapidly rotating even-even Nd132-138 isotopes have been investigated using the pairing-deformation self-consistent total-Routhian-surface calculations in a deformation space of (beta(2), gamma, beta(4)). It is found that even-even Nd134-138 nuclei exhibit triaxiality in both ground and excited states, even up to high-spin states. The lightest isotope possesses a well-deformed prolate shape without a gamma deformation component. The current numerical results are compared with previous calculations and available observables such as quadrupole deformation beta(2) and the feature of gamma-band levels, showing basically a general agreement with the observed trend of gamma correlations (e.g. the pattern of the odd-even energy staggering of the gamma band). The existing differences between theory and experiment are analyzed and discussed briefly. |
