    "abstract": "We have realized a two-species mirror-magneto-optical trap containing a\nmixture of $^{87}$Rb ($^{85}$Rb) and $^{133}$Cs atoms. Using this trap, we have\nmeasured the heteronuclear collisional loss rate $\\beta_{Rb-Cs}\u0027$ due to\nintra-species cold collisions. We find a distinct difference in the magnitude\nand intensity dependence of $\\beta_{Rb-Cs}\u0027$ for the two isotopes $^{87}$Rb and\n$^{85}$Rb which we attribute to the different ground-state hyperfine splitting\nenergies of the two isotopes.",
