Abstract
The recent success of BEC in rubidium, lithium and sodium has led us to
reinvestigate the collisional properties of cesium, that define the
circumstances for BEC. We analyze a set of cold-collision data,
comprising atomic fountain frequency shifts and elastic scattering
rates, to determine phase parameters that completely characterize cold
collisions between two ground-state atoms. Very interesting in this case
are the surprisingly large decay rates of atoms polarized in the highest
state of the upper and lower hyperfine manifold(J. Söding, D.
Guéry-Odelin, P. Desbiolles, G. Ferrari, and J. Dalibard
(unpublished).)^,(J. Söding and J. Dalibard, Priv. Commun.). We
show these decay rates can be described consistently with the other data
by taking into account an indirect spin-spin interaction, where
collisional resonances play an essential role. We discuss circumstances
where BEC in cesium might be achievable.
