摘　　要：利用碱金属原子与理想金属表面间范德瓦尔斯(vd W)作用势和不可约张量方法,导出超精细能级中碱金属原子特定量子态C3的解析表达式,完成133CS原子62D3/2(F=2,3,4,5)的C3数值计算,计算结果表明随着的增大,C3增大,z(原子与金属表面之间的距离)不变时,铯原子与理想金属表面间vd W作用增强.同时对于由电四极矩作用产生的C31效果因贡献不显著,C3数值结果并未见到有异常波动现象.By utilizing alkali atoms and perfect surface of a metal between Van der Waals （vdW） interaction and irreducible tensor method. We get analytical expression of coefficient C3 of hyperfine levels of alkali atoms. C3 values corresponding to hyperfine levels of 133C excited states （62D3/2 （F = 2,3,4,5 ） ） are calculated. It is also shown that, the greater the F, the larger the C3, and the stronger the vdW interaction when z does not change, where z is the distance of an atom from the metal surface. At the same time for C31 effect is produced by the elec- tric quadrupole moment because of no significant contribution, C3 numerical results did not meet with abnormal fluctuations.
