In this paper we review the present status on heteronuclear trap loss
rate (
) for alkali mixtures held in a magneto-optical
trap (Na-K, Na-Rb, Na-Cs, K-Rb, Rb-Cs, Li-Cs). The intensity dependence
of the for the mixture Cs-K is also presented
for the first time in this report. The measurement techniques and a
semiclassical model, considering both excited-ground and doubly excited
channels, are reviewed. The comparison between the model and the experimental
results indicates that radiative escape may be the dominant loss process for
heteronuclear cold collisions. The obtained values for the crossed species
trap loss indicate possibilities of future experiments involving such mixtures
in a two species condensate.
