Description of Nuclear Properties for 114-128Cd Isotopes

Abstract

In this paper, the energy levels of the ground-state band (GSB) and other states for 114−128Cd isotopes have been determined using the Interacting Boson Model (IBM-1) with a New Empirical Equation (NEE). The GSB results showed that the IBM-1, NEE, and available experimental data were all in fairly consistent. The NEE and IBM-1 calculations for the high states above 6+ state are slightly overestimated compared to the experimental data, with the exception of the 114Cd and 118Cd nuclei. Furthermore, the reduced transition probabilities B(E2) extracted from the IBM-1 model agree well with the available experimental data. The potential energy surface (EPS) was also examined with the IBM-1. The EPS contour results for Cd isotopes demonstrate that the Cd isotopes under investigation represent a smooth transition behavior from light Cd nuclei toward a more collective vibrational mode as the neutron number increases.
