The excitation energy and the oscillator strength values have been computed for the $1s^2$–$1s2p$, $1s2s$–$1s2p$, $1s2s$–$1s3p$ transitions in the helium isoelectronic sequence ($Z=2$ through $Z=116$). The importance of the Breit interaction and radiative corrections to the oscillator strength as well as transition energies have been studied. The method of calculations was based on the relativistic hydrogen-like (with non-integer nuclear number) wavefunctions.

氦等电子序列低能态跃迁的相对论结构相互作用计算

激励能量和振荡器强度值已经计算出 $\mathrm{1个}{s}^2$–$\mathrm{1个}s2p$， $\mathrm{1个}s2s$–$\mathrm{1个}s2p$， $\mathrm{1个}s2s$–$\mathrm{1个}s3p$ 氦等电子序列中的跃迁（$ž=2$ 通过 $ž=116$）。研究了Breit相互作用和辐射校正对振荡器强度以及跃迁能量的重要性。计算方法基于相对论的类氢（具有非整数核数）波函数。
