摘要：

We discuss the low-energy shape oscillations of a magnetically trapped atomic condensate including the spin dipole interaction. When the nominal isotropic s-wave interaction strength becomes tunable through a Feshbach resonance (e.g., as for Rb-85 atoms), anisotropic dipolar effects are shown to be detectable under current experimental conditions [E. A. Donley , Nature (London) 412, 295 (2001)].
