Two-Center Basis Generator Method Calculations for Li3+, C3+ and O3+ Ion Impact on Ground State Hydrogen

The two-center basis generator method is used to obtain cross sections for excitation, capture, and ionization in Li3+, C-3+,C- and O3+ collisions with ground-state hydrogen at projectile energies from 1 to 100 keV/u. The interaction of the C3+ and O3+ projectiles with the active electron is represented by a model potential. Comparisons of cross sections with previously reported data show an overall good agreement, while discrepancies in capture for C3+ collisions at low energies are noted. The present results show that excitation and ionization are similar across the three collision systems, which indicates that these cross sections are mostly dependent on the net charge of the projectile only. The situation is different for the capture channel.
