Rigid Triaxial Rotor Model Description of γγ-Band in Some Even Nuclei

NUCLEAR STRUCTURE ^104,106,108Mo, ¹¹²Ru, ^154,156Gd, ^160,162Dy, ¹⁹²Os, ¹⁷⁸Hf; calculated odd-even staggering (OES) in γγ-band in rigid triaxial rotor model (RTRM); deduced the OES in γ-band and γγ-band obtained from rigid triaxial rotor model (RTRM) are constant for an axial rotor and staggering appears in same phase for a rotor with large triaxial deformation. Comparison with experimental data.
