Excitation cross sections in a collision between two ground-state hydrogen atoms

Abstract

We present excitation cross sections in collision between two ground state hydrogen atoms using a four-body classical trajectory Monte Carlo model. Calculations were performed for impact energies in the range between 1.0 keV and 100 keV where the cross sections are highly relevant to the interest of the fusion research. Beside the total excitation cross sections for target and projectile we also present partial excitation cross sections into the 2s and 2p states of the target. The partial excitation cross sections are compared with the previously obtained theoretical and experimental results.
