Abstract

We present theoretical calculations of thermally averaged elastic cross sections and spin relaxation rates in the temperature range 1 {micro}K to 300 {micro}K for magnetically trapped doubly polarized Cesium atoms. The calculations reproduce the recent experimental results of Arndt et al. (1997) and Soeding et al. (1998) for cases where the a³Σ_u ground state potential of Cs₂ possesses a large scattering length (|A₃| > 35 nm) and the magnitude of the second-order spin-orbit interaction is scaled to reproduce room temperature scattering data.
