- Abstract
This paper proposes an improved potential for the β -part of the collective Bohr Hamiltonian, namely, a Killingbeck plus Morse potential, while the γ -part is solved for a triaxial deformation close to γ = 3 0 ∘ . The Asymptotic Iteration Method is used, involving the Pekeris approximation, to calculate the energy eigenvalues and the eigenfunctions after an exact separation of the Bohr Hamiltonian into its variables is achieved. The results of these calculations are applied for energy spectra of the low-lying states and for corresponding B (E 2) quadrupole transition probabilities of the 1 9 2 , 1 9 4 , 1 9 6 P t isotopes. Moreover, the results of the present solution are compared with those of the well-known Z (5) and e s M models.
