Proton-hydrogen collisions: Differential and total cross sections for H(2s) and H(2p) production in the 1—7 keV range

摘要: A multistate molecular approach to the proton—hydrogen collision is formulated in terms of an impact parameter perturbed stationary-states approximation. Spurious long range couplings are avoided and Galilean invariance enforced by inclusion momentum translation factors which determined variationally within Euler-Lagrange formalism (Crothers & Hughes 1978). Well defined radial rotational coupling matrix elements employed 1-7 keV energy a six-state (lso g , 2po u 2pπ 3po 3pπ 4fo ) calculation elastic inelastic differential scattering cross sections, charge exchange probabilities both direct H (2p) production total sections. They also same ten-state (1so 3dπ 2so 3do 4dπ (2s) The results excellent accord with experimental data show considerable improvement on previous calculations. This success attributed elements.
