Description
A second Born treatment is applied to study the (e, 3e) and (e, 3 - 1e) reactions for H2 targets. The results of this approximation are compared to the (e, 3 - 1e) experimental data obtained at about 600 eV impact energy. Several single-centre wavefunctions are used to describe the initial state and excited states of the molecule. Even if the second Born approximation is able to explain part of the experimental results the agreement is not good, similar to the case of the double ionization of helium (Goetz et al 2003 J. Phys. B: At. Mol. Opt. Phys. 36 L77)
