Screening of a flow of evaporated metal atoms by the Langmuir layer formed at the point of contact of hot plasma with metal

We have theoretically analyzed conditions under which the screening of a flow of evaporated metal atoms by the Langmuir layer formed due to ionization of atoms in this layer can significantly influence the dynamics of hot plasma in contact with a metal surface. It is established that allowance for the screening of evaporated atomic flow by this Langmuir layer is necessary in many cases, in particular, in simulations of laser-plume dynamics.
