Light-induced drift of a one-component gas in a channel
Abstract
The paper examines the light-induced drift of a one-component gas in a channel excited by radiation which is selective with respect to the molecule velocities. The drift is due to the difference in the interaction between the walls and the excited or unexcited particles. The problem is solved analytically for molecular or atomic absorption lines of arbitrary shape and for an arbitrary deactivation law at the wall. The distribution functions and estimates of drift velocity, temperature, and heat flux in the gas are obtained.
