Abstract

Application of the straight‐line impact parameter method is made to scattering of ions (atoms) on molecules at energies E_c.m.≳10 eV. Two different quantum versions of a DECENT‐like model are applied to calculate integral and differential excitation cross sections for H⁺+H₂ scattering on the lowest diabatic singlet surface. We find good agreement with experimental data and with other theoretical results.
