Abstract [en]

Total-Routhian-surface calculations by means of the pairing-deformation-frequency self-consistent cranked shell model have been carried out for even-even germanium and selenium isotopes to search for possible stable triaxial deformations of nuclear states. The maximum triaxiality of |gamma| approximate to 30 degrees. is found in the ground and excited rotational states of the nuclei (64,74)Ge. The calculations are compared with available experimental data, giving a general agreement with observed triaxiality in the isotopes.
