Sameer M. Ikhdair, Ramazan Sever

摘要:

本文用Nikiforov-Uvarov方法近似求解了具有经验势函数的双原子分子转振(转振)运动的薛定谔方程。计算了近似的振转能谱和相应的归一化全波函数的封闭形式,并用超几何函数或Jacobi多项式P_{n} ^{(μ,ν)}(x)表示,其中μ>-1,ν>-1,x包含在[-1,+1]中.得到了s波的解析解。对选定的H_{2}和Ar_{2}分子的数值能量本征值也进行了计算,并与以前的模型和实验进行了比较。

英文摘要:

The Schrodinger equation for the rotational-vibrational (ro-vibrational) motion of a diatomic molecule with empirical potential functions is solved approximately by means of the Nikiforov-Uvarov method. The approximate ro-vibratinal energy spectra and the corresponding normalized total wavefunctions are calculated in closed form and expressed in terms of the hypergeometric functions or Jacobi polynomials P_{n}^{(μ,ν)}(x), where μ>-1, ν>-1 and x included in [-1,+1]. The s-waves analytic solution is obtained. The numerical energy eigenvalues for selected H_{2} and Ar_{2} molecules are also calculated and compared with the previous models and experiments.
