We report the calculation of the interspecies scattering length for the sodium-rubidium (Na-Rb) system. We present improved hybrid potentials for the singlet X{sup 1}{sigma} {sup +} and triplet a{sup 3}{sigma}{sup +} ground states of the NaRb molecule, and calculate the singlet and triplet scattering lengths a{sub s} and a{sub t} for the isotopomers {sup 23}Na{sup 87}Rb and {sup 23}Na{sup 85}Rb. Using these values, we assess the prospects for producing a stable two-species Bose-Einstein condensate in the Na-Rb system.
