Abstract:

On the basis of the self-consistently determined diabatic quasiparticle representation, RPA calculations in the rotating frame are performed for the γ-vibrations around the triaxial equilibrium shapes. The doubly stretched quadrupole forces are used as residual interactions. It is found that the negative-signature γ-vibrational modes created on the s-band well retain their collective characters, while the positive-signature modes tend to lose their identities with increasing rotational frequency.
