{"publisher":"American Physical Society","abstract":[{"lang":"eng","text":"We present an analytic model of the refractive index for matter waves propagating through atomic or molecular gases. The model, which combines the Wentzel-Kramers-Brillouin (WKB) treatment of the long-range attraction with the Fraunhofer model treatment of the short-range repulsion, furnishes a refractive index in compelling agreement with recent experiments of Jacquey [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.98.240405 98, 240405 (2007)] on Li atom matter waves passing through dilute noble gases. We show that the diffractive contribution, which arises from scattering by a two-dimensional &quot;hard core&quot; of the potential, is essential for obtaining a correct imaginary part of the refractive index."}],"author":[{"full_name":"Mikhail Lemeshko","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"},{"full_name":"Friedrich, Břetislav","first_name":"Břetislav","last_name":"Friedrich"}],"oa":1,"month":"08","citation":{"short":"M.
