Abstract：
The properties of γinstability in rapidly rotating even-even ^132-138Nd isotopes have been investigated using the pairing-deformation self-consistent total-Routhian-surface calculations in a deformation space of ( β ₂, γ, β ₄). It is found that even-even ^134-138Nd 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 γdeformation component. The current numerical results are compared with previous calculations and available observables such as quadrupole deformation β ₂and the feature of γ-band levels, showing basically a general agreement with the observed trend of γcorrelations (e.g. the pattern of the odd-even energy staggering of the γband). The existing differences between theory and experiment are analyzed and discussed briefly.
