Direct measurement of He+ ions produced by Compton scattering between 2.5 and 5.5 keV.
J.A.R. Samson,J.A.R. Samson,Z.X. He,Z.X. He,R. J. Bartlett,R. J. Bartlett,M. Sagurton,M. Sagurton +7 more
TL;DR: By measuring the number of He[sup +] ions produced with near zero recoil energies it was possible to identify ions produced by Compton scattering from those produced by photoionization.

Excitation-ionization and double ionization of helium by Compton scattering
TL;DR: The behavior of the cross section for inelastic photon scattering in the limit of high but nonrelativistic photon energies at helium leading to two-electron transitions is investigated and the ratio of double to single ionization is determined.

TL;DR: In this article, the authors present cross sections for double ionization of helium by alpha-particle impact within the independent-event model, and the calculated cross sections in the present model show excellent agreement with the measurement of Shah and Gilbody (1985), at all energies above 200 keV amu-1.
