THE RELAXATION OF STRONG ELECTRON EXCITATIONS IN SOLIDS INDUCED BY MULTICHARGED ION-BOMBARDMENT

The relaxation of electron ''citations arising from irradiation by multicharged ions of metals and insulators is considered. The excitation processes in solids are described. In metals, the relaxation is determined by the electron thermal conductivity, and electron energy transfer to the lattice is small. In insulators, the electron excitation relaxation is dependent on the low temperature ionization wave, the electron heat is localized, and lattice atoms receive enough energy for melting. The electron-phonon interaction at high electron temperatures and lattice relaxation is considered.
