Popis: | The elastic scattering properties for collisions between ultracold Na and K atoms in the singlet state are investigated. Based on the recent theoretical and experimental results, the improved hybrid potential is presented for the singlet X1 Σg+ ground state of NaK. By means of the Numerov and semiclassical methods, the values of the s-wave scattering length a for the singlet state are calculated to be 33.3757a0 and 37.9399a0, respectively. Pronounced shape resonances appear for the l = 1 partial wave for the X1 Σg+ state. In addition, the s-wave scattering cross section, total cross section and energy positions of shape resonances for the X1 Σg+ state are discussed. |
