• A pulsed beam of metastable argon atoms having a low tunable velocity (10 to 150 m s−1) is produced with a very substantial brightness (9  ×  108Ar* s−1 sr−1). The present original experimental configuration leads to a variable velocity dispersion that can be smaller than the standard Brownian one. This behaviour, analysed using Monte Carlo simulations, exhibits momentum stretching (heating) or narrowing (cooling) entirely due to a subtle combination of Doppler and Zeeman effects.
