Abstract

The odd-even staggering (OES) in γγ-band in rigid triaxial rotor model (RTRM) is investigated at different asymmetry. It is found that the OES in γ-band and γγ-band obtained from rigid triaxial rotor model (RTRM) are different with some details, essentially, they are similar: both of them are constant for an axial rotor and staggering appears in same phase for a rotor with large triaxial deformation. The onset of zigzag behavior of staggering indices S(I) in γγ-band appears from S(8) at γ = 25° however, in γ-band from S(8) at γ = 15°. Thus, similar OES curve in theory and experiment at specific asymmetry for an individual nucleus in γγ-band may be the criterion to distinguish γ-rigid or γ-soft structure of nucleus, not the alternate positive and negative values of S(I). The experimental OES in γγ-band for some even nuclei is calculated and compared with rigid triaxial rotor model predictions and their structure has been commented.
