IBM-2 calculations for even-even cadmium isotopes

Abstract EN

The structure of some even-even Cd isotopes has been studied using the neutron-proton interacting boson model(IBM-2).

Theoretical calculations of the energy levels were fitted, the transition probabilities and the multipole mixing ratios for some selected transitions were obtained and compared with the experimental results.

The set of model parameters used in this work suggest that most of the Cadmium isotopes are vibrational.

The behaviors of the set of parameters in the Hamiltonian were studied as a function of neutron number across the transitional region, notably c k n , which indicated manifestly the change of shape of these isotopes from vibrational to almost rotational.

The present results are in a good agreement with the experimental work.
