摘要

用超对称量子力学方法讨论了广义Kratzer 势的形状不变性,并计算了它的能量本征值.传统的Kratzer 势和改进的Kratzer 势都是广义Kratzer 势的特例.在此基础上,计算了双原子分子CO 和NO 在不同的径向量子数nr和角量子数l 时的能量本征值的具体数值.

Abstract

Using super - symmetric quantum mechanics arguments,the shape invariance of the generalized Kratzer potential is discussed,and its energy eigenvalues are calculated. Both the traditional Kratzer potential and the modified Kratzer potential are the special cases of the generalized Kratzer potential. On this basis,the exact eigenvalues of the diatomic molecules such as CO and NO for various values of radial quantum number nr and angular quantum number l are calculated numerically.
