Investigation of Adsorption and Wetting of He-3 on Cesium and Cesiated Glass
Résumé
Experiments have been carried out to investigate the binding of He-3 on cesium substrates, using optical pumping to spin-polarize the atoms. The behaviour of He-3 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 He-3 on cesiated glass; (ii) magnetic relaxation time of polarized liquid He-3 on cesium and cesiated glass; (iii) evidence for wetting of liquid He-3 on cesium.
