Projectile angular distribution in single ionization of helium by proton impact at high and intermediate energies

The CDW-EIS theoretical method is applied to explain recent measurements of helium single ionization by proton and deuteron impact. This theory can cope with the proton angular distribution data for a wide range of projectile energy from 100 keV amu-1 to 6 MeV amu-1. At intermediate energies the CDW...
