Ionisation of H2 by fast protons and multiply charged ions of He, Li, C, N and O

A crossed-beam coincidence technique has been applied to studies of non-dissociative and dissociative ionisation of H2 by protons and multiply charged ions. Cross sections σsub(ni) for nondissociative ionisation and cross sections σsub(di) for the sum of the dissociative ionisation channels have been separately determined for 38-1500 keV amu-1 H+,31-550 keV amu-1 He2+,30-388 keV amu-1 Lisup(q+) with 1 <=q<=3, 16-193 keV amu-1 Csup(q+) with 2<=q<=4, 14-166 keV amu-1, Nsup(q+) with 2<=q<=5 and 12-145 keV amu-1 Osup(q+) with 2<=q<=5. Measured cross sections are dependent on and increase with q. Peak values of σsub(ni) and σsub(di) shift to higher velocities as q increases. (author)
