- Abstract
- In this study, Bohr Hamiltonian is studied for the triaxial and rotational cases. In both cases, Killingbeck potential is used as interaction. The wave function and energy of these cases are found using bi-confluent Heun functions. The results are examined by reproducing experimental data of some isotopes for each case. Energy levels of the isotopes are shown graphically as well as theoretical results for staggering in gamma bands of the isotopes is discussed. In the next step, we argue about B(E2) transition rates of the isotopes for each case. The results have a good agreement with experimental data. (C) 2018 Elsevier B.V. All rights reserved.
