Abstract

Measurements of simultaneous ionization and excitation of ground-state helium to the 2p state of the helium ion by electron impact are presented by observing electron-photon coincidences between the 30.4-nm photon radiation and a scattered outgoing electron. Our results are then compared with theoretical calculations.
