We address a growing interest in trapping and cooling of mixed-species alkali-metal atoms. Long-range coefficients that arise in the multipole expansion of molecular potentials for unlike alkali-metal dimers are calculated. The coefficients for the heteronuclear alkali-metal dimers corresponding to different molecular symmetries that separate to nS-n8S ,nS-n8P ,nS-n8D , and nP-n8P atomic levels are computed with high precision. We consider cases where in the infinite separation limit, one atom… CONTINUE READING
