Abstract

In this work, We investigate the energy levels and the electromagnetic transition probabilities B(E2) and B(M1) for Eu-155 within framework of IBFM-2. The results are in reasonably agreement with the available experimental values. The result of an IBFM-2 multilevel calculation with the 3s1/2, 2d3/2, 2d5/2, and 1g7/2 single particle orbits is reported for the positive parity states of the odd-mass Eu-155 isotopes. Also, an IBM-2 calculation is presented for the low-lying states in the even-even Sm-154 core nucleus.

Keywords
