Lyman-α line polarization after proton impact on atomic hydrogen

New experimental and theoretical data for the degree of linear polarization of Lyman-α emission induced by proton and antiproton impact on atomic hydrogen in the 1–1000 keV impact energy range are presented. For the calculations a two-centre extension of the basis generator method is used to solve the time-dependent Schrödinger equation. In the experimental part we present new measurements for the polarization fraction of the impact induced Lyman-α radiation in the energy range from 13 keV to 800 keV for the collision system p + H. The calculated polarization fractions are in very good agreement with the experimental data.
