Abstract: | On the basis of the longitudinal field Green function, in a three-layer non-symmetrical system of media with spatial dispersion the image-force potential is calculated for surfaces of the semi-infinite helium bath and a liquid helium film, and also for a surface of the phase-separated 3He4He mixture. The dependence of the surface electron spectrum on the film thickness and on the pressing electric field strength is analyzed. |
