We describe and test experimentally a setup allowing efficient optical pumping of laser-cooled cesium atoms into the F=4, m=0 ground-state Zeeman sublevel, which is insensitive to magnetic perturbations. High resolution Raman stimulated spectroscopy is shown to produce Fourier-limited lines, allowing, in realistic experimental conditions, atomic velocity selection to one-fifth of a recoil velocity.
