    "abstract": "We report the calculation of the interspecies scattering length for the\nsodium-rubidium (Na-Rb) system. We present improved hybrid potentials for the\nsinglet $X^1\\Sigma^+$ and triplet $a^3\\Sigma^+$ ground states of the NaRb\nmolecule, and calculate the singlet and triplet scattering lengths $a_{s}$ and\n$a_{t}$ for the isotopomers $^{23}$Na$^{87}$Rb and $^{23}$Na$^{85}$Rb. Using\nthese values, we assess the prospects for producing a stable two-species\nBose-Einstein condensate in the Na-Rb system.",
