Abstract

We have realized a two-species mirror-magneto-optical trap containing a mixture of $^{87}$ Rb ( $^{85}$ Rb) and $^{133}$ Cs atoms. Using this trap, we have measured the heteronuclear collisional loss rate $\beta_{Rb-Cs}'$ due to intra-species cold collisions. We find a distinct difference in the magnitude and intensity dependence of $\beta_{Rb-Cs}'$ for the two isotopes $^{87}$ Rb and $^{85}$ Rb which we attribute to the different ground-state hyperfine splitting energies of the two isotopes.
