We consider optical pumping with a quasi monochromatic tunable light beam, in the low intensity limit where a rate equation regime is obtained The velocity selective optical pumping (V.S.O.P.) introduces a correlation between atomic velocity and internal variables in the ground (or metastable) state. The aim of this article is to evaluate these atomic observables (orientation, alignment, population) as a function of velocity, using a phenomenological description of the relaxation effect of collisions. The V.S.O.P. line shapes, obtained by scanning the pumping beam frequency and using a counterpropagating detection beam with the same frequency, are given in various circumstances. The combination of V.S.O.P. with modulated pumping, magnetic r...
