CCC calculated integrated cross sections of electron-H$_2$ scattering

Recently we applied the molecular convergent close-coupling (CCC) method to electron scattering from molecular hydrogen H$_2$ [1]. Convergence of the major integrated cross sections has been explicitly demonstrated in the fixed-nuclei approximation by increasing the number of H$_2$ target states in the close-coupling expansion from 9 to 491. The calculations have been performed using a projectile partial wave expansion with maximum orbital angular momentum $L_{\rm max}=8$ and total orbital angular momentum projections $|M| \leq 8$. Coupling to the ionization continuum is modeled via a large pseudo state expansion, which we found is required to obtain reliable elastic and excitation cross sections. Here we present benchmark elastic, single-ionization, electronic excitation and total integrated cross sections over a broad energy range (0.1 to 300 eV) and compare with available experiment and previous calculations.
