Abstract
The reflection properties of a semi-infinite plasma in the presence of a magnetic field normal to its surface are calculated on the assumption that the response of the electrons is governed by Fermi-liquid theory and that the surface of the plasma randomizes the motion of the electrons incident upon it. A resonancelike magnetic field dependence of the surface impedance is found near that field for which propagation of the correlation-produced magnetoplasma mode first becomes possible. The size of the structure is calculated to be much enhanced over that of the corresponding structure calculated using specular scattering as a boundary condition for the electrons. Numerical and analytic results are presented and discussed for a range of parameters relevant to possible experiments in the alkali metals.
