In this paper, we present a summary of our work in progress on calculating cross sections for the He+H¯→Hep¯+e+ rearrangement process in HeH¯ scattering. This has involved a study of the system Hep¯ within the Born–Oppenheimer (BO) approximation using the Rayleigh–Ritz variational method. This work has been reported in [A.C. Todd, E.A.G. Armour, J. Phys. B 38 (2005) 3367] and is summarised here. Similar calculations are in progress for the He+H¯ entrance channel.We intend to use the entrance channel and rearrangement channel wave functions to obtain the cross sections for the rearrangement using the distorted wave Born approximation T-matrix method described elsewhere in these proceedings [E.A.G. Armour, S. Jonsell, Y. Liu, A.C. Todd, these Proceedings, doi:10.1016/j.nimb.2006.01.049].
