Abstract

The properties of γ\gamma instability in rapidly rotating even-even 132138^{132-138}Nd isotopes have been investigated using the pairing-deformation self-consistent total-Routhian-surface calculations in a deformation space of (β2,γ,β4\beta_2, \gamma, \beta_4). It is found that even-even 134138^{134-138}Nd nuclei exhibit the triaxiality in both ground and excited states, even up to high-spin ones. The lightest isotope possesses a well-deformed prolate shape without γ\gamma deformation component. The current numerical results are compared with previous calculations and available observables, showing basically a general agreement with the observed trend of γ\gamma correlations. The existing differences between theory and experiment are analyzed and discussed briefly.
