Va. Yerokhin et al., Interelectronic-interaction effect on the radiative recombination of an electron with a heavy He-like ion - art. no. 042712, PHYS REV A, 6204(4), 2000, pp. 2712
Interelectronic-interaction correction of first order in 1/Z is studied for
radiative recombination of an electron with a heavy He-like ion in the gro
und state. A rigorous relativistic treatment is compared with two frequentl
y applied approximations. A calculation is carried out for radiative recomb
ination of an electron into 2s, 2p(1/2), and 2p(3/2) states of He-like uran
ium for impact energies between 10 and 700 MeV/u.
