摘要: 用超位力定理(HVT)和赫尔曼-费恩曼(Hellman—Feynman)定理(HFT)计算了Coulomb势加上径向线性项和常数项的本征能量的微扰系数,这种计算方法优于通常的瑞利-薛定谔微扰理论,不需要计算本征函数系数,并且用这种方法可以既快捷又有效地计算大量本征能量的微扰系数.

Abstract: Using the Hellman - Feynman (HF) and Hypervirial (HV) theorems, the perturbative coefficients of the eigenenergies are calculated in the case of Coulomb potential with a radial linear term and a constant term. The calculation method, excel to the usual Rayleigh- Schroedinger perturbation theory (RSPT), does not require the calculation of eigenfunctions coefficients. This method is a fast and efficient tool for the calculation of large order eigenenergies coefficients.

Key words: perturbation theory, Coulomb potential, eigenenergies
