TDHF calculations for two-electron systems

TDHF calculations using a two-centre basis expansion technique are carried out for two-electron systems in the energy range of 5 to 40 keV/nucleon. Cross sections are calculated for one-electron capture of p+He(1s 2 ) and for one- and two-electron capture of He 2+ and Li 3+ from He(1s 2 ) and compared with other theoretical and experimental results. The influence of the exchange potential is briefly traced by considering the collision systems He + (2s)+He + (2s) and He + (2s)+H(1s) for the spin-singlet and spin-triplet cases.
