Abstract
A molecular study of the excitation reactions H(1s)+H(1s)→H(1s)+H(2s) and H(1s)+H(1s)→H(1s)+H(2p) is presented for the first time in the range of impact energies 1–9 keV, using a common translation factor to account for the momentum-transfer problem. As a consequence of this study, we explain in detail the collisional mechanisms involved and point out several new features that may explain the discrepancies between the available experimental data and all previous theoretical calculations, and among the latter. Preliminary results for the cross sections are also presented to show the influence of the form chosen for the common translation factor.Keywords
