用半经典方法推得碱金属原子价电子自旋一轨道相互作用能公式、双层能级间隔公式等。从理论计算可知电偶极和电四极极化所引起的精细结构裂距很小。对n=13、l=5的量子态理论值与实验值基本相符。 相似文献

Different classes of first-principle pseudopotentials are compared and various schemes for pseudopotential generation based
on norm conservation are discussed in this paper. BHS (Bachelet, Hamann, and Schlüter)-scheme and V (Vanderbilt)-modifications
are used to derive the KB (Kleinman and Bylander)-pseudopotentials and pseudo wave functions of bismuth. Quality test of pseudopotentials
shows that no ghost states occur in the logarithmic derivatives of pseudo wave functions of Bismuth. The obtained bond length
of bismuth dimer with this type of pseudopotentials is in good agreement with previous accurately calculatedab initio quantum chemical result.
