We report results on inelastic cold collisions for a mixed species magneto-
optical trap containing Na and Rb. The rate of collisional trap loss of Na
is due to different contributions: Na-Na and Na-Rb collisions. Both parts a
re investigated with respect to trap laser intensity and frequency. The obs
ervations are explained based on a Gallagher-Pritchard model. Possibilities
for studies and applications involving mixed species traps are discussed.
