摘要：

Cross sections for the nondissociative single ionization and double ionization of H2 by He2+ projectiles in the range of 125 750 keV/amu are reported. The results are compared to impact-parameter calculations and to measurements with He+ projectiles. The direct double-collision process is found to be the important contributor to double ionization in this range of energies. The single-ionization cross section, when compared to proton bombardment, does not scale as Z2. © 1990 The American Physical Society.
