摘要

We have treated the \(\textrm{H}^+ + \textrm{H}^-\) H + + H - collisions using atomic-orbital close-coupling calculations within the impact-parameter method. Cross sections for single electron transfer, electron detachment, transfer ionization, and double electron transfer are calculated for collision energies from 0.3 to 30 keV. The calculated results are generally in accord with the experimental data, but the result for transfer ionization is significantly larger than the experimental data below 1.5 keV.
