摘要：

Differential cross sections were determined for the production of H- fragments produced by the collision of H2+ on Kr at projectile energies between 1.0 to 5.0 keV and for scattering angles from -4-degrees to 4-degrees. The H- distributions are observed to fit to the scaling law (1/E)d sigma/dOmega = F(E theta2), where E is the incident energy. Two structures found at 4.0 and 7.3 eV yield information about the production of H-. These are associated with the direct dissociation and predissociative states of H2+ interacting with the target.
