Abstract
Detailed double-differential distributions in energy and angle of emission of electrons ejected into the continuum by collisional ionization of projectiles with He are measured. Anisotropies of the resulting three-dimensional cusps are discussed in terms of contour lines taken at different levels. They show a structure that calls for an inclusion of higher terms in the expansion of the cross section, not contained in first Born calculations of Day and of Briggs and Day.
