Abstract
H(2s) formation in collisions between ground-state hydrogen atoms for impact energies in the region 1-9 keV is investigated. By allowing for rotation of the internuclear axis in a two-state non-adiabatic theory the authors obtain results on the 1s to 2s single-transition cross section. The results obtained are compared with previous theoretical calculations and with experimental data. They believe this to be the first correct theoretical treatment of exchange for this process.Keywords
