We present an approach for calculating the H-2 vibrational distribution, electron energy distribution function and negative ion concentration (H-) based on the self-consistent solution of the vibrational master equation and of the Boltzmann equation. Most of the input data of the present model have been obtained by our group in these last years by using classical, semiclassical and quantum approaches. In particular we discuss the most important process involving vibrationally excited H2 molecules colliding with themselves as well as with atomic hydrogen, electrons and metallic surfaces. Part of these data have been obtained by using dynamic calculations. The main result of our approach, which mixes different techniques, is the ability of reproducing the main experimental features of negative ion (H-) sources.
