Absolute differential and total cross-sections for the production of H+ and H-0 fragments in the energy range of 1-5 keV and scattering angles from -4.6 degrees to 4.6 degrees, for the collision of H-2(+) on SF6 are reported. The differential and total cross-sections for dissociative capture 2 (DC) and collision-induced dissociation (CID) were estimated. The differential cross-sections (DCS) of DC and CID for all acceleration energies show a monotonic decrease with increasing angle, showing an overall decrease of three and two orders of magnitude for DC and CID respectively. The total cross-section for the DC process is found to be in the range of 10.0-40.0 angstrom(2), while for the CID process it is between 0.8 and 2.3 angstrom(2). Both measured total cross-sections display a slowly increasing behavior as a function of the incident energy. The results show that the cross-section for the DC process is about 13.2 times higher in average than that for the CID process. (c) 2007 Elsevier B.V. All rights reserved. |
