Abstract
In a crossed-beam experiment the vibrational excitation of H2 by proton impact has been measured at a scattering angle of 0 degrees (angular resolution +or-0.5 degrees ) and in the energy range 15 to 120 eV (CM system). The spectra show resolved vibrational transitions nu =0 to nu ' with nu '=1, 2, 3 and 4. The measured energy dependences of the differential cross sections for all four vibrational transitions are characterised by an oscillatory behaviour superimposed on a linearly rising function. The results of first calculations for the nu =0 to 1 transition are in very satisfactory agreement with the experimental data.Keywords
