N2 - We have measured the index of refraction for sodium de Broglie waves in gases of Ar, Kr, Xe, and [Formula presented] over a wide range of sodium velocities. We observe glory oscillations—a velocity-dependent oscillation in the forward scattering amplitude. An atom interferometer was used to observe glory oscillations in the phase shift caused by the collision, which are larger than glory oscillations observed in the cross section. The glory oscillations depend sensitively on the shape of the interatomic potential, allowing us to discriminate among various predictions for these potentials, none of which completely agrees with our measurements.
