Ultracold collisions of Cs atoms in excited Zeeman and hyperfine states
Abstract
We investigate Cs +Cs scattering in excited Zeeman and hyperfine states. We calculate the real and imaginary parts of the s -wave scattering length; the imaginary part directly provides the rate coefficient for two-body inelastic loss, while the real part allows us to identify regions of magnetic field where three-body recombination will be slow. We identify field regions where Cs in its (f ,mf) =(3 ,+2 ) and (3 ,+1 ) states may be stable enough to allow Bose-Einstein condensation, and additional regions for these and the (3, 0) and (3 ,-3 ) states where high-density clouds should be long-lived.
