Experiments have been carried out to investigate the binding of 3 He on cesium substrates, using optical pumping to spin-polarize the atoms. The behaviour of 3 He on the walls at low temperature can be analyzed through the evolution of the nuclear magnetization of the sample. Preliminary results are presented, including: (i) adsorption studies of gaseous 3 He on cesiated glass; (ii) magnetic relaxation time of polarized liquid 3 He on cesium and cesiated glass; (iii) evidence for wetting of liquid 3 He on cesium.
