Cross sections for the nondissociative single ionization and double ionization of H{sub 2} by He{sup 2+} projectiles in the range of 125--750 keV/amu are reported. The results are compared to impact-parameter calculations and to measurements with He{sup +} 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 {ital Z}{sup 2}.
