The explicit expressions of energy eigenvalues and eigenfunctions of bound
states for a three-dimensional diatomic molecule oscillator with a
hyperbolic potential function are obtained approximately by means of the
hypergeometric series method. Then for a one-dimensional system, the
rigorous solutions of bound states are solved with a similar method. The
eigenfunctions of a one-dimensional diatomic molecule oscillator, expressed
in terms of the Jacobi polynomial, are employed as an orthonormal basis set,
and the analytic expressions of matrix elements for position and momentum
operators are given in a closed form. 相似文献
