Abstract

A short-lived density grating is produced in a gas of lithium atoms. The gas is preliminarily cooled in a magnetooptical trap. The grating is formed due to diffraction of atoms on a standing light wave. The grating is observed from Bragg’s scattering of light from it. This method of formation and observation over the grating can be used in a lithium-based atomic interferometer.
