赵等提出了双η型的二价铜离子的经验径向波函数,相继有文、计算了C_u~(++)的晶场谱等,后有文用于Fe~(++),而徐、赵文更进一步称为3d-径向波数,用以计算Cr~(+++)的晶场参量Dq 与红宝石的R_1线。我认为以上工作皆属不当,兹提出如下评论。一、对于单电子体系,因无电子之间的相互作用,即不用Racah 参量A、B、C 而仅用晶 Zhao et al. Proposed the empirical radial wave function of double n-type divalent copper ions. The crystal field spectra of C_u ~ (++) Xu, Zhao Wen further referred to as the 3d - radial wavenumber, used to calculate Cr ~ (+++) of the crystal field parameters Dq ruby ​​R_1 line. I think the above work is all improper. I hereby submit the following comments. First, for a single electron system, because there is no interaction between electrons, that is, without Racah parameters A, B and C, only the crystal
