【摘要】 本文给出了类氦等电子系列离子n^1,8S和n^1,3P态统一的半经验能量计算公式,此公式是通过拟合Ermold6v和Jones关于类氦离子2≤Z≤42最低谱项（n=2—5）的计算值得到的。根据本文提供的公式,可以予言任何n^1,3S和n^1,3P高激发态能级值及相应能级之间跃迁的波长值,对一些ls²一lsnp跃迁波长将本文的计算值与实验值进行了比较,结果表明除个别外在实验误差范围内两者十分吻合,此外还对类氦等电子系列离子量子数亏损的规律性进行了详细的讨论。更多还原

【Abstract】 In this paper an unified semi-empirical formulae for the energy structure of HeI-like spectra n~1,3S and n1,3 P has been given.It was derived by fitting Ermolaev and Jones’ calculated results for the HeI-like ions 2≤Z≤ 42,which, include the absolute term values of the ls2 1S ground level and the lsns and lsnp levels for n=2 through 5.The wavelengths of all transitions associated with n1,3 S and n1,3 P can thus be predicated for these spectra.The predicated and observed results for some ls2-lsnp trasition are compared.the different changing rules of the quantum defects of HeI-like sequence spectra for n1,3S and n1,3P are also discussed and explained.更多还原
