    "abstract": "We have measured the index of refraction for sodium de Broglie waves in gases\nof Ar, Kr, Xe, and nitrogen over a wide range of sodium velocities. We observe\nglory oscillations -- a velocity-dependent oscillation in the forward\nscattering amplitude. An atom interferometer was used to observe glory\noscillations in the phase shift caused by the collision, which are larger than\nglory oscillations observed in the cross section. The glory oscillations depend\nsensitively on the shape of the interatomic potential, allowing us to\ndiscriminate among various predictions for these potentials, none of which\ncompletely agrees with our measurements.",
