IBM-1calculations of energy levels and electric transition probabilities B(E2)‎ in “158-160Gd isotopes”

Abstract EN

In this paper, the interacting boson model (IBM-1) is described and employed for calculating the energy levels and electric transition probabilities B(E2) for “158-160Gd isotopes”.

The values of the parameters have been determined using the IBM-1 Hamiltonian which yield the best fit to the available experimental energy levels.

Particular attention has been paid to the B(E2) transition probabilities.

In general, a good agreement has been achieved between the IBM-1 calculations and the available experimental results of energy levels and B(E2) values.

The results showed that the “158-160Gd isotopes” are rotational (deformed) nuclei and that they have dynamical symmetry SU(3) in the interacting boson model IBM-1.
