Reconstruction of a charged helium film on a metallic substrate

Peculiarities of the reconstruction of a charged helium film surface on a metallic substrate are considered. Instability evolution in this case resembles the generation of a solitary wave in hydrodynamics of a free liquid surface and leads to the formation of charged solitons under certain conditions. Basic characteristics of such solitons are obtained in the one-dimensional approximation under the conditions of weak nonlinearity of the problem. (C) 1997 American Institute of Physics.
