Abstract

The elastic scattering properties of cold atoms are very sensitive to the details of the interatomic potentials.Based on recent theoretical and experimental investigations,the research presents improved hybrid potentials for the singletX1 ∑g+and tripleta3∑u+ground states of the6Li2by the cubic spline interpolation and extrapolation.The calculated values for the scattering lengths are compared with previous results,and good agreements are obtained.The scattering lengths are 36.5a0for the singlet state and-2138.74a0for the triplet state.

Accurate calculation of the elastic scattering properties of 7 Li atoms at ultralow temperatures

Sun Jin-Feng, Zhang Ji-Cai, Jiemin Wang

The elastic scattering properties for collisions between two 7 Li atoms are investigated in the cold and ultracold regimes separately. Based on recent theoretical and experimental results, we present the improved hybrid potentials for the singlet X 1 ∑ g + and triplet a 3 ∑ u + ground states of the Li 2 . Our calculated values for the scattering lengths a and the effective ranges r e are compared with previous ones and found them to be in good agreement. The scattering lengths are 34.6 a 0 for the singlet state and −27.6 a 0 for the triplet state. Shape resonances occur in the collisions at low energies. We also calculate the total cross sections and the energy positions of shape resonances for both X 1 ∑ g + and a 3 ∑ u + states.

Calculation of the elastic scattering properties for cold and ultracold 39 K atoms in a triplet state

Hu Qiu-Bo, Wang Xiao-Fei, Sun Jin-Feng +1 more

The elastic scattering properties for collisions between cold and ultracold 39 K atoms in a triplet state are investigated. Based on the recent theoretical and experimental results, the improved hybrid potential is presented for a triplet a 3 ∑ u + ground state of K 2 . Our calculated value of the s-wave scattering length a by using the Numerov method for the triplet state is 79.578 a 0 and found to be in good agreement with the previous ones. The numbers of bound states are supported by the molecular potential. Pronounced shape resonances appear for the l = 3 partial waves for the a 3 ∑ u + state. Furthermore, the s-wave scattering cross section, the total cross section and energy positions of shape resonances for the a 3 ∑ u + state are calculated.

Calculation of scattering parameters for ultracold 6 Li— 7 Li elastic collisions

Jicai Zhang, Jinfeng Sun, Yufang Liu

This paper theoretically studies the elastic scattering properties in a mixture of 6Li and 7Li atoms at cold and ultracold temperatures. Based on the constructed accurate interatomic potential of the triplet state for 6Li7Li mixture by the mass scaling method, it calculates the interspecies s-wave scattering lengths and the p-wave scattering lengths by the variable phase method and the semiclassical method, respectively. The scattering length is in good agreement with the experiment. The partial-wave and total cross sections are also calculated and a rich resonance structure is found.

Elastic Scattering of Ultracold 23 Na and 39 K Atoms in the Singlet State

Hu Qiu-Bo, Zhang Yong-Sheng, Sun Jin-Feng

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 X 1 Σ g + 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 33.3757 a 0 and 37.9399 a 0 , respectively. Pronounced shape resonances appear for the l = 1 partial wave for the X 1 Σ g + state. In addition, the s-wave scattering cross section, total cross section and energy positions of shape resonances for the X 1 Σ g + state are discussed.

Accurate calculation of elastic scattering properties of ultracold sodium atoms

Zhang Ji-Cai, Zhu Zun-L uuml e, Sun Jin-Feng

Based on the accurate singlet and triplet state interatomic potentials for Na2, a theoretical study of elastic scattering properties of sodium atoms at ultracold temperatures is reported in this paper. The s-wave scattering length, effective range, the p-wave scattering length and the number of bound states are calculated. The singlet and triplet elastic scattering cross section between sodium aotms at ultracold temperatures are dominated by s-wave scattering, and shape resonances occur with collision energy increasing. There exist pronounced f-wave and i-wave shape resonances for the singlet and triplet cross section. In addition, s-wave scattering length is calculated by using the degenerate internet state approximation for selected hyperfine states of sodium atoms. The results are in agreement with calculated values obtained by close-coupling method.

Calculation of Elastic Scattering Properties in Ultracold Fermi–Bose and Bose–Bose Rb–K Vapor

Mustafa Kemal Öztürk, Süleyman Özçelik

The calculation of the elastic scattering properties of mixtures composed of ultracold Rb–K atoms is reported and compared with experimental results in detail. The improved potentials for both the singlet and triplet molecular states of Rb–K are presented, and the scattering lengths a t and the effective range r e are calculated with numeric and semiclassical methods for Rb–K in the triplet and singlet state. In addition, the convergence of these scattering properties depending on a K 0 parameter is investigated using quantum defect theory. Other results of the evaporative cooling that include the cross section and the spin–charge cross section, the rate coefficient as a function of the energy and ultralow temperature are also presented in this study.
