Abstract

In this study, the SU(3) rotational limit of interacting boson model is employed in calculating 156-162 Dy isotopes energy levels and electromagnetic transition rates between these levels. The 0,2, 4+, 6+ ground state band, 0, 25.45 B band and 2, 3, 4 y band energy levels of Dy isotopes are calculated. In addition, B(E2) transition probability values and B(E2;2→0)/B(E2;4→2) transition rates are obtained for these isotopes. The calculated values have been compared with other theoretical calculations and experimental results. It has been observed that the obtained results are agreement with the other results in literature.
