摘要: A two-centre expansion in travelling atomic orbitals is employed to investigate H+-H- collisions at energies and above 8 keV (lab) for which electron exchange between the hydrogen atoms formed neutralisation reaction unimportant. In addition H++H- channel, terms representing H(n=2)+H(1s) H(n=3)+H(1s) are included wavefunction together with a number of pseudostate designed overlap hydrogenic continuum. The calculated cross sections agreement high previous calculations based on one-electron model by Ermolaev (1985), also agree quite well 8-10 data Gaily Harrison (1970).
