摘　　要：讨论了外激光场中氢原子修饰势的奇点．为了解Schrodinger方程，提出了一种新的迭代方法．对于圆偏振情况，引进了一种旋转坐标，从而消去了哈密顿量中的时间变量，因此Schrodinger方程变成定态形式．对激光场中氢原子修饰态的准能级进行了数值计算．基态和低激发态的准能级随外激光场参量αc的变化比较显著，而高激发态的准能级则变化很慢．The singular point of the dressed potential of H-atoms in an applied laser field wasdiscussed. In order to solve the Schrdinger equations, an iteration method was presented. For thecircular polarization, a rotation coordinate was introduced which eliminated the time-variable in theHamiltonian, so that the Schrodinger equation becomes stationary. The quasi - levels for dressed statesof H-atoms in laser fields were computed. The obvious variations of quasi-levels of ground andlower- excited states with the parameter ac. of the applied laser field are observed, whereas thequasi -levels of higher-excited states vary slightly.
