Abstracts

EN

It is demonstrated that free-carrier plasmons being well defined collective excitations of the electron gas in the range of small wave vectors can serve as a sensitive tool to investigate the optical processes related to the small momentum transfers. As an example the system HgSe:Fe is analysed both experimentally and theoretically.
