Time-dependent Hartree-Fock calculations for the He+(1s)+He+(1s) system

Time-dependent Hartree-Fock calculations are performed for the two-electron system He + (1s)+He + (1s) in the centre-of-mass energy range 5-80 keV. One-electron capture cross sections are calculated for the M s =0 and mod M s mod =1 channels and compared with experimental results. The Pauli blocking for the n=2 shell is briefly discussed.
