Abstract

Doubly differential cross sections (ddcs), for ejection of secondary electrons of various energies and at various angles from helium bombarded by fast protons, have been calculated using the Born approximation. The wave functions of helium are approximated by products of one-electron orbitals. Results for the ddcs are given for several different choices of the one-electron orbitals, and these are compared with recent experimental values corresponding to 200- and 300-keV incident protons.
