Abstract
The elastic and the 2s and 2p inelastic scattering of ground-state hydrogen atoms by helium is examined in the Born, unitarized-Born and multistate impact-parameter formulation of heavy-particle collisions, with incident energies E in the range 6.25<or=E<or=225 keV. The failure of Born's approximation to provide an adequate description of both small angle elastic and inelastic scattering and large-angle inelastic scattering is graphically displayed.Keywords
