【摘要】 用旋转坐标方法消除了圆偏振激光场中氢原子哈密顿量中的时间变量。定态薛定谔方程经变量分离后可用来计算光场中氢原子的准能级值。用 Numerov 方法计算了低频圆偏振激光场中氢原子准能级随光场参数 a₀的变化。a₀=A₀/cω,式中 A₀是光场矢势的振幅,ω是光场的频率,c 是光速常数．结果表明,准能级位置随 a₀增加而升高,并接近于零．更多还原

【Abstract】 By using of the rotary-coordinate system,the time variable in the Hamilto- nian of hydrogen atoms in the laser field with circular polarization was e- liminated.By means of the separation of variables,the stationary Schrclinger equation can be used for calculating the quasi-level of hydro- gen atoms in laser field.Using Numerov method,the variation of the quasi-level of hydrogen atoms with the parameter a₀ of baser field with cir- cular polarization at low frequency had been calculated,Where a₀=（A₀）/（cω）,Ao is the vector potential amplitude of laser field,ω is the frequency of it,and c is the speed of light the result of calculation shows that the positions of quasi-levels raise with the increase of a₀,and approach to zero.更多还原
