摘要：
A general expression was obtained for the dynamic energy of the van der Waals interaction of a neutral atom with a flat slit whose walls are characterized by a frequency-dependent dielectric permittivity. The interaction of cesium atoms with the walls of metallic (Au) and dielectric (SiC) slits is analyzed numerically at speeds of 10(4) to 10(7) m/s. As the speed of atoms grows, the dynamic potentials near the walls become substantially smaller in magnitude than static potentials, but, in the intermediate region, the former exceed the latter by a factor of 1.5-2.0 in a specific range of speeds.
