    "abstract": "We report here the first measurements of the index of refraction of gases for\nlithium waves. Using an atom interferometer, we have measured the real and\nimaginary part of the index of refraction $n$ for argon, krypton and xenon, as\na function of the gas density for several velocities of the lithium beam. The\nlinear dependence of $(n-1)$ with the gas density is well verified. The total\ncollision cross-section deduced from the imaginary part is in very good\nagreement with traditional measurements of this quantity. Finally, as predicted\nby theory, the real and imaginary parts of $(n-1)$ and their ratio $\\rho$\nexhibit glory oscillations.",
