Abstract Scattering properties of ultracold atoms are sensitive to the interatomic potential. Based on the accurate triplet least-bound state energy, we calculate the triplet s-wave scattering length for 23Na–40K. The scattering length is ?814.1?31.3+29 a0 with a0 being the Bohr radius. By using the mass scaling method, those scattering lengths are also obtained for 23Na–41K and 23Na–39K. The degenerate internal state approximation is used to estimate the scattering data of atoms colliding in different spin states.
