Is Bose-Einstein condensation of atomic cesium possible?
Laboratoire Kastler Brossel - 24 rue Lhomond, 75005 Paris, France
Accepted: 6 August 1998
We investigate the dipole relaxation of a cesium atomic gas prepared in its lowest hyperfine level (F=3) and confined in a magnetic trap. We measure a rate , for a field of 0.1 mT and a temperature 1 . This value is 2 orders of magnitude larger than for lighter alkalis. It puts strong constraints on the trapping mechanism which could lead to the Bose-Einstein condensation of cesium.
