It is shown that the frequencies of logitudinal electric oscillations in solids satisfy the condition (ω)=0, where (ω) is the dielectric constant for the frequency ω/2π which can be obtained from the optical constants n, κ. Such longitudinal waves include so-called plasma oscillations. It is shown that energy losses of fast charged particles in discrete steps hω p (the plasma quantum) can be expected only if the quantity nκ/( n 2 + κ 2) 2 has a sharp maximum at a frequency ω p.

1 Electric polarization and dielectrics Here I want to consider the basic theory for induced electric dipoles in matter, and how that leads to the electric permittivity (ω). In optical systems, it is clear that the response of a medium to the radiation fields, i.e., photons, induces electric dipoles, and those in turn could react back on the.
