Abstract

In this paper, IBM-1 and IBM-2 with a SU(3) limit are used to describe the 158Gd isotope. The calculations of energy levels in the ground state, beta-, and gamma-bands are made up, which account for 15 energy levels. However, we found that the energy states of the same spin of the beta- and vibrational bands become degenerate states. In breaking the SU(3) dynamical symmetry by introducing a value of pairing interaction, the degeneracy is lifted and the energy levels are brought up to the same order as the experimental ones.

158Gd核的能级和衰变性质描述

本文采用SU(3)极限的IBM-1和IBM-2来描述158Gd同位素。计算了基态、β和γ波段的能级，共占15个能级。然而，我们发现相同自旋和振动带的能量状态变成简并态。通过引入对相互作用值打破SU(3)动力学对称，提高了简并度，使能级上升到与实验能级相同的阶数。
