Exactly solvable potential with four parameters for diatomic molecules
Wuli Xuebao/Acta Physica Sinica(1999)
摘要
A four-parameter potential function is proposed. The corresponding s-wave Schrödinger 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.
