摘要：
New experimental and theoretical data for the degree of linear polarization of Lyman-alpha 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 Schrodinger equation. In the experimental part we present new measurements for the polarization fraction of the impact induced Lyman-a 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.
