Differential cross sections for ionisation of helium by proton impact

A wave-packet convergent close-coupling approach is applied to study differential ionisation in proton-helium collisions. The fully differential cross sections for electrons ejected with energy of 5.4 eV are investigated in 75 keV proton-helium collisions. We also study the doubly differential cross sections for electrons ejected with energies up to 65 eV at intermediate projectile energies (50-150 keV). The results are converged regarding the number of pseudostates included and are in fairly good agreement with the available experimental data.
