The electron-capture process p + H2 H(1s) + H+2 (1ss) is described using distorted-wave-Born models by considering the influence of the vibrational motions of H2 and H2 + within the framework of the Born-Oppenheimer approximation. Non-dissociative and dissociative capture cross sections are calculated for incident proton energies EC=20-300 keV. The vibrational distribution of H+2 (1ss) is compared with that of the Franck-Condon factor. They are in fairly good agreement for EC < 100 keV, and discrepancies arise for higher EC.
