A molecular potential model is proposed and the solutions of the radial Schrӧdinger equation in the presence of the proposed potential is obtained. The energy equation and its corresponding radial wave function are calculated using the powerful parametric Nikiforov-Uvarov method. The energies of cesium dimer for different quantum states were numerically obtained for both negative and positive values of the deformed and adjustable parameters. The results for sodium dimer and lithium dimer were calculated numerically using their respective spectroscopic parameters. The calculated values for the three molecules are in excellent agreement with the observed values. Finally, we calculated different expectation values and examined the effects of the deformed and adjustable parameters on the expectation values.
提出了一种分子势模型，并得到了在所提出的势存在下径向薛定谔方程的解。利用强大的参数化尼基福罗夫 - 乌瓦罗夫方法计算了能量方程及其相应的径向波函数。对于变形和可调参数的正负值，数值得到了不同量子态下铯二聚体的能量。使用钠二聚体和锂二聚体各自的光谱参数对它们进行了数值计算。这三种分子的计算值与观测值非常吻合。最后，我们计算了不同的期望值，并研究了变形和可调参数对期望值的影响。
