Absolute cross sections for the ionization-excitation of helium by electron impact

Bellm, Susan; Lower, Julian; Weigold, Erich; Bray, Igor; Fursa, D.V; Bartschat, Klaus R; Harris, A.L; Madison, Don Harvey


In a recent publication we presented detailed experimental and theoretical results for the electron-impactinduced ionization of ground-state helium atoms. The purpose of that work was to refine theoretical approaches and provide further insight into the Coulomb four-body problem. Cross section ratios were presented for transitions leading to excited states, relative to those leading to the ground state, of the helium ion. We now build on that study by presenting individual relative...[Show more]
