  The two-center basis generator method is used to obtain cross sections for
excitation, capture, and ionization in Li$^{3+}$, C$^{3+}$, and O$^{3+}$
collisions with ground-state hydrogen at projectile energies from 1 to 100
keV/u. The interaction of the C$^{3+}$ and O$^{3+}$ projectiles with the active
electron is represented by a model potential. Comparisons of cross sections
with previously reported data show overall good agreement while discrepancies
in capture for C$^{3+}$ 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.
