我们计算了铷原子在超冷温度下的散射特性,特别强调放射性同位素 Rb、Rb、Rb 和 Rb。与更“传统”的同位素 Rb 结合,这些物质会产生各种各样的散射行为,从而产生费米-费米、费米-玻色和玻色-玻色气体的混合物。在这些混合物中的每一种中,我们都发现至少一种情况可以使用外部磁场来调整种间散射长度。这些结果将大大拓宽量子简并气体在未来实验中的前景。 @S1050-2947~99!06802-X#
We compute the scattering properties of rubidium atoms at ultracold temperatures, placing special emphasis on the radioactive isotopes Rb,Rb,Rb, and Rb. In combination with the more ‘‘conventional’’ isotope Rb, these species yield a wide variety of scattering behavior, with consequences for creating mixtures of Fermi-Fermi, Fermi-Bose, and Bose-Bose gases. In each of these mixtures we find at least one case where the interspecies scattering lengths can be tuned using an external magnetic field. These results should greatly broaden the prospects for quantum degenerate gases in future experiments. @S1050-2947~99!06802-X#
