Abstract

The partial photoionization cross sections and the angular distribution asymmetry parameter for photoelectrons ejected from helium in the transitions to the n=2 states of the He⁺ ion are calculated for incident photon energies from just above the threshold to 160.6 eV. Good agreement is obtained with experiment.
