We have measured the photoionization-excitation-to-photoionization ratio for He + n (n = 2-6) at several photon energies from 90 to 900 eV. By extrapolating these values we could determine the asymptotic high-energy ratios for He + n (n = 2-5) which agree with theoretical predictions. We show that the satellite-to-main-line ratios are consistent with experimental double-to-single photoionization ratios and agree well with recent measurements. ¶doi:10.1088/0953-4075/30/2/004 fatcat:fm4sa6zizbcmfpuysjkvayeomu
