AN ALTERATIVE METHOD OF ADIABATIC VARIATIONAL CALCULATION OF HYDROGEN ENERGY IN A STRONG MAGNETIC FIELD 

采用绝热近似和变分原理，引入描述Ｃｏｕｌｏｍｂ作用的等效模型势，给出绝热变分方程，计算了均匀强磁场（１≤β≤２０００）中氢原子的基态和几个较低激发态的能级，并与绝热近似方法和公认为最精确的类多组态ＨａｒｔｒｅｅＦｏｃｋ方法的结果进行了比较，给出的基矢比Ｌａｎｄａｕ基矢具有更好的收敛性．

Abstract In this article,by using the adiabatic approximation and variational principle and introducing an effective potential we have computed some energy levels of hydrogen atom in the presence of a strong magnetic field(1≤ β ≤2000) and compared our results with the like multi configuration Hartree Fock method.We found a basic function with better convergence than the Landau function.
