Phys. Rev. A 63, 052704 (2001) [4 pages]High-precision calculations of van der Waals coefficients for heteronuclear alkali-metal dimersReceived 29 November 2000; published 12 April 2001 van der Waals coefficients for the heteronuclear alkali-metal dimers of Li, Na, K, Rb, Cs, and Fr are calculated using relativistic ab initio methods augmented by high-precision experimental data. We argue that the uncertainties in the coefficients are unlikely to exceed about 1%. © 2001 The American Physical Society URL:
