An experimental atomic physicist who coauthored a 1952 report on optical pumping with Jean Brossel and Alfred Kastler. Selective absorption of light redistributes population among ground-state Zeeman effect sublevels, preparing an atomic ensemble whose magnetic-state populations differ from thermal equilibrium. This connects control of incident light to preparation and readout of atomic angular momentum.[ref]
