An investigation of low-energy proton on hydrogen collisions

摘要: The proton on hydrogen collision problem is treated in the time-dependent formalism using a new self-consistent nuclear-trajectory model conjunction with simple semiclassical approximation. In this method nuclear trajectory dependent time evolution of electronic wavefunction which described by basis H2+ eigenfunctions. small-energy large-scattering-angle region well way and agreement available experimental data obtained. inclusion approximation use larger molecular than hitherto employed allow these limits to be quite reasonably extended describe small-angle moderate-energy also. Results charge-exchange probabilities differential scattering cross sections range 150-1000 eV (laboratory energy incident beam) are presented along some inelastic calculations excitation into 2p+or-1 2s states. gerade states (2s sigma g,3d g) set has significant effect results obtained for energies 700 1 keV.
