基态原子与理想金属Au表面间的范德瓦尔斯作用及超精细能级C3的估算
Van der Waals interaction between ground state atoms and perfect surface of a metal and calculation of C3 in hyperfine atomic levels
摘要
Abstract
Van der Waals (vdW)interaction between alkali atoms and perfect surface of a metal Au is investigated. Taking into account the contribution to vdW from the electric quadruple,a theoretical model is presented to calcu-late C3 values of the vdW interaction between hyperfine levels of alkali atoms and perfect surface of a metal.C3 val-ues corresponding to hyperfine levels of 85 Rb and 133 Cs are calculated,where C3 values of 52 S1/2 (F=2)and 52 S1/2 (F=3)for 85 Rb are 2.2409KHzμm3 and 2.2425 KHzμm3 ,respectively,while 62 S1/2 (F=3)and 62 S1/2 (F=4)for 133 Cs 2.4480 KHzμm3 and 2.4538KHzμm3 .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. This research on atomic imprisoned and quantum reflection from the dielectric surface has certain significance.关键词
