Abstract

The collisional scattering of magnetically polarized atoms is of fundamental interest since the scattering process couples translational and internal degrees of freedom.1 Photon-echo techniques have recently been used to study this coupling by preparing active atoms in a superposition of magnetic sublevels and then quantitatively correlating collisional velocity changes with collisional depolarization.2–5 These experiments provide previously unmeasured information about the collision process. For example, they elucidate the differential relaxation experienced by different types of magnetic order (k-multipoles) and clarify the structure of polarization preserving collision kernels.
