Abstract
Five recently measured 4He i transitions involving nS, nP, and nD levels (n = 3–8, Δn = 0, 2) are compared with theoretical energy levels having estimated uncertainties that are comparable with those of the experimental results (~10−3 cm−1) [ T. J. Sears, S. C. Foster, and A. R. W. McKellar, J. Opt. Soc. Am. B 3, 1037 ( 1986)]. The agreement between theory and experiment is generally good, but a considerable discrepancy exists for one transition.
