Direct scattering ({r_arrow}H{sup 0}), stripping ({r_arrow}H{sup +}), and electron capture ({r_arrow}H{sup {minus}}) are studied at energies of 1.0, 2.0, and 3.0 keV in small-angle H{sup 0}+N{sub 2} collisions. Time-of-flight and electrostatic-energy analysis are used to identify the dominant collision processes. The electronically elastic channel is found to be weak beyond the very smallest scattering angles. As an example, at 1.0 keV, electronically inelastic processes dominate the collision for scattering angles larger than 0.2{degree}. Beyond the smallest angles, both the stripping and electron-capture processes can also result in electronic excitation of the N{sub 2} or N{sub 2}{sup +}. The reduced cross sections, when plotted as a function of reduced scattering angle, are shown to scale reasonably well for each of the three processes studied. {copyright} {ital 1996 The American Physical Society.}
