冷碱金属原子间相互作用势的研究

Research on the Atomic Interaction Energy Between Cold Alkali Atoms

近年来,研究冷和超冷原子碰撞已经由相同原子扩展到了异核原子领域。针对^(113)Cs和^(85)Rb原子的碰撞,构建了两种异核原子间相互作用势,这两种势有相同的相移。另外,对^(39)K原子间相互作用势进行实验和理论上的研究,构建了目前为止最精确的相互作用势能曲线。基于构建的势能曲线,并对^(133)Cs和)^(85)Rb原子以及两^(39)K原子间的冷和超冷碰撞特性进行了详细的研究,得到了非常满意的结果。

In recent years, researches on cold and ultracoid atoms have expanded from the same kind of atoms to the realm of atomic mixtures. According to the collision between Atom 133Cs and Atom 85Rb, it establishes the interaction energy between the two-kind atomic mixtures which are connected by the same phase shift. Furthermore, it constructs the by now most accurate Interaction Potential Curve on the base of the experimental and theoretical studies on the interactions between 39K atoms. Based on the curve, detailed studies have been carried out on the cold and ultracold collision characteristics between Atom 133Cs and Atom 85Rb and between two 39K atoms, which has achieved satisfactory results.
