Abstract
The differential and total cross sections for single charge exchange in p + He collisions have been calculated by means of the Born distorted wave (BDW-4B) approximation. The BDW-4B model is a four-body quantum-mechanical distorted-wave theory. The computations of total cross sections are carried out at impact energies ranging from 40 keV to 15 MeV. The differential cross sections are calculated at impact energies covering 50, 100, 150, 200, 293, 300 and 400 keV. The theoretical results obtained for the differential and total cross sections are compared with the available experimental data and good agreement is found.
