Query: Differential Scattering and Rethermalization in Ultracold Dipolar Gases   Analytic expressions for the differential cross sections of ultracold atoms
and molecules that scatter primarily due to dipolar interactions are derived
within the first Born approximation, and are shown to agree with the partial
wave expansion. These cross sections are applied to the problem of
cross-dimensional rethermalization. Strikingly, the rate of rethermalization
can vary by as much as a factor of two, depending on the orientation of
polarization of the dipoles. Thus the anisotropic dipole-dipole interaction can
have a profound effect even on the behavior of a nondegenerate ultracold gas.
