Projectile angular distribution in He single ionization by proton impact as a function of the ejected-electron energy

In this paper we study the single ionization of helium atoms by the impact of protons at intermediate energies. We present a continuum-distorted-wave–eikonal-initial-state calculation of the cross section doubly differential in the projectile scattering angle and the ionized electron energy. The int...
