Specific features of the passage of atomic and molecular beams through capillary structures while interacting with surface light wave

A model of the transverse cooling of atoms in the field of a surface light wave inside a glass capillary is considered. The attenuation coefficient for transverse oscillations of an atom in a microcapillary is estimated, and the length of effective atom cooling to the energy ħ2 k 2/2M is calculated. A 3D model is constructed. The possibility for the practical application of this phenomenon to the creation of the technology of atomic lithography and the fabrication of nanostructures is considered.
