摘要：
In this work, we study the collective Bohr Hamiltonian of triaxial nuclei within deformation-dependent mass formalism (DDM) using the new Anharmonic potential. The Schrodinger equation with Bohr Hamiltonian is separated into two parts and the beta-part is solved by mean of Nikiforov-Uvarov method to obtain the energy spectra. The gamma-part is defined by a ring shape potential and solved with the same method. The energies and the B(E2) transition rates for nuclide Pt-192,Pt-194,Pt-196 are calculated and compared with the experimental data and with some others models in the same formalism.
