Abstract

The energy distributions of H+ fragments produced in N7+ + H2 collisions at projectile energies ranging from 1.4 keV down to 32 eV have been investigated experimentally as a function of the detection angle. At 1.4 keV, two groups of peaks are clearly visible, especially at forward angles. The structure centered at energies lower than ∼ 20 eV, corresponds to a double capture at relatively large impact parameters, whereas the highly energetic protons result from capture events at very small impact parameters. The results from a quasiclassical calculation method show a good agreement with our experimental data for the fragment energy distributions. At the lowest projectile energy, the fragment energy is found to be independent on the detection angle.
