Light-induced diffusion of gases
Gel'mukhanov F.Kh., Shalagin A.M.
A new effect of light-induced diffusion of gases is reported. This effect basically can be described as follows: a monochromatic traveling wave, upon absorbing atoms in the transition from the ground state, induces a macroscopic diffusion flux of absorbing atoms moving in the direction of or opposite to the light flux. As a result, the atoms collect at the end of the absorbing container in a <l-mm-thick layer.
