严格可解四参数双原子分子势函数

EXACTLY SOLVABLE POTENTIAL WITH FOUR PARAMETERS FOR DIATOMIC MOLECULES 

提出一个四参数双原子分子势函数，对ｓ 波 Ｓｃｈｒⅹｄｉｎｇｅｒ 方程进行了严格求解，并采用一个简便的方法考虑了转动修正．该势函数对实验 Ｒｙｄｂｅｒｇ Ｋｌｅｉｎ Ｒｅｅｓ 曲线及振动转动能级的计算精度远优于常用的 Ｍｏｒｓｅ 势，且将 Ｍｏｒｓｅ 势等势函数作为特例包括于其中．

A four\|parameter potential function is proposed.The corresponding s \|wave Schrdinger equation is solved exactly,and the rotational energy is approximately considered by using a simple method.The evaluating accuracy of the potential for the experimental RKR curve and the rotational\|vibrating level is far better than the usual Morse potential,and the latter is contained in this potential as a special case.
