摘要：
The elastic scattering properties in a mixture of sodium and cesium atoms are investigated at cold and ultracold temperatures.Based on the accurate interatomic potential for the NaCs mixture,the interspecies s-wave scattering lengths,the effective ranges and the p-wave scattering lengths are calculated by the quantal method and the semiclassical method,respectively.The s-wave scattering lengths are 512.7a 0 for the singlet state and 33.4a 0 for the triplet state.In addition,the spin-change and elastic cross sections are also calculated,and the g-wave shape resonance is found in the total elastic cross sections.
