The cross sections for the double ionization, ionization plus excitation, and double excitation of H{sub 2} by electrons and protons in the range of 350 to 3500 keV/amu have been measured. In all cases, the cross section for electron bombardment was greater than that for equivelocity proton bombardment. The results are discussed in terms of first and second Born processes and interferences between the two.
