Abstract
In this paper, the nuclear structure of ground-state bands of even-even Cd104-122 isotopes has been reviewed under the framework of interacting boson model-1 (IBM-1). The theoretical energy levels for Z = 48, even N = 56-74 up to 8(+) state have been obtained by using the PHINT computer program. The values of the parameters in the IBM-1 Hamiltonian yield the best fit to the experimental energy spectrum. The results are compared with the most recent experimental values where an acceptable degree of agreement is achieved. In this paper, the properties of even Cd104-122 isotopes have been considered to the U(5) similar to SO(6) transitional region of the IBM-1.
