Dissipation of the energy of a fast charged particle in a solid-state plasma

Results are presented from experimental investigations of mechanisms for the dissipation of the energy of light ions in metal plasmas by using the method of secondary electron emission. It is shown that the coefficient of anisotropy of energy transfer from fast light ions is about 1.7. It is also shown that plasma oscillations excited by an ion significantly influence the production and emission of low-energy electrons, especially in the case of projectile molecular ions.
