氢原子第二激发态的多极动态极化率和两体色散系数

Multipole dynamic polarizabilities and two-body dispersion coefficients of atomic hydrogen in the second excited state

基于径向库仑格林函数的积分性质,严格导出了处于第二激发态的氢原子的2′极动态极化率的解析表达式,绘出了处于第二激发态的氢原子的电偶极、电四极和电八极动态极化率随光场频率变化的曲线图.在此基础上,用两种不同的方法计算了H(3s)-H(3s)体系的两体色散系数,两种方法的计算结果相当一致.

Based on the integral properties of the radial Coulomb Green＇s function, an exact and analytic expression is derived for the 2t -pole dynamic polarizabilities of atomic hydrogen in its second excited state, typical results for dynamic dipole, quadrupole and octupole polarizabilities at real photon frequen- cies are shown in a series of figures. The two-body dispersion coefficients for H（3s）-H（as） system are thus calculated by two different methods, the results agree well with each other.
