Abstract The elastic scattering properties between ultracold 23Na and 85Rb atoms for the triplet state (a3∑u+) are researched. The s−wave scattering lengths of 23Na and 85Rb are calculated by the Numerov and semiclassical method with two kinds of interatomic potentials, which are the interpolation potential and Lennard–Jones potential (LJ12,6) by the same phase ϕ. Shape resonances appear clearly in the l=5 partial waves for the a3∑u+ state. Moreover, the s-wave scattering cross section, total cross section and energy positions of shape resonances are also discussed.
