We have performed the first detailed calculation of the index of refraction of a gas (argon) for
an atomic wave (sodium). The index depends rapidly on the wave vector kr describing the …

This paper describes new theoretical results and calculations concerning the recently
introduced index of refraction of a gas for atomic waves. More precisely, the motion of the …

We have measured the index of refraction for sodium de Broglie waves in gases of Ar, Kr,
Xe, and N 2 over a wide range of sodium velocities. We observe glory oscillations—a …

Two different formulas relating the index of refraction n of gases for atom waves to the
scattering amplitude have been published. We show here that these two formulas are not …

Two experiments are presented which measure atomic properties using an atom
interferometer. The interferometer splits the sodium de Broglie wave into two paths, one of …

We report the first measurements of the index of refraction of gases for lithium waves. Using
an atom interferometer, we have measured the real and imaginary parts of the index of …

By inserting a gas cell in one arm of an atom interferometer, we have measured both the
attenuation and the phase shift of a sodium matter wave that passes through monatomic …

We present a theoretical study of the index of refraction of argon for the propagation of
sodium matter waves. The sensitivity of the index of refraction to the details of the molecular …

We use the Kramers–Kronig dispersion relation to calculate the real part of the index of
refraction of neon and argon for energies ranging from zero into the x-ray region. The cross …

We present a theoretical study of the index of refraction of the light noble gases He and Ne
for the propagation of sodium matter waves. Our approach is based on the well known …
