Abstract : At moderate kinetic energies up to about 50 eV of the incident ion, the velocity spectra agree with the predictions of the stripping model. At higher energies, the bands of the product ions are shifted to somewhat higher velocities. This indicates preferential forward scattering of the charged reaction product and less conversion of kinetic energy of the incident ion into internal energy of the products. As was expected, the cross sections for the transfer of an H- and D-atom are equal at the same relative kinetic energy. Over a wide range of energy, the cross section depends on the relative kinetic energy as sigma = k1 . c to the (-k2Es) power. Reactions could still be observed at relative kinetic energies, which are larger than the dissociation energy of the product ion (up to 7 eV for N2H(+) and N2D(+) and up to 10 eV for COH(+) and COD(+)). These details of the collision mechanism are tentatively explained by two hypotheses. (Author)
