摘要: 利用SD配对壳模型研究了质量数A~130区原子核的低激发态性质。为了减少参数，模型采用了等强度对力，取质子和中子对力强度等同近似，而非同类核子间的四极-四极相互作用强度取为同类核子间四极-四极相互作用强度的两倍。计算结果显示，模型的振动-转动和振动-γ不稳定运动的形状渡越特征与相互作用玻色子模型对应的形状相变特征基本吻合，从而说明SD配对壳模型是壳模型的一种合理近似。

The SD-pair shell model is applied to analyze the evolution of low-lying states of even-even nuclei in A~130 mass region. In the model, the pairing and the quadrupole-quadrupole interactions are taken into account. The results show that there are clear signatures of the crossover from vibrational to rotational or from vibrational to the γ-soft shape phase.
