    Cross sections as functions of impact energy for TE to He(1s2s1S, 1s2p1P, and 1s3s1S) excited states.
    Cross sections as functions of impact energy for TE and ET to He(1s2s 1S, 1s2p 1P, and 1s3s 1S) excited states. Note that the ET cross sections were presented in Ref. 4.
    Cross sections as functions of impact energy for TE to He(1s2s3S, 1s2p3P, and 1s3s3S) excited states.
    Cross sections as functions of impact energy for PE to He∗+(n = 2) states. Note that the data for PE to the He∗+(2p) state was presented in previous work.4
