Abstract

Using the COLTRIMStechnique, scattering angle differential cross sections for single and double electron capture in collisions of protons and He\sp1,2+ projectiles with helium atoms for incident energies of 60-630 keV/u are measured. We also report new theoretical results obtained by means of four-body one-channel distorted wave models (CDW-BFS, CDW-BIS and BDW), and find mixed agreement with the measured data.
