Concerning the electromagnetic radiation spectrum of a hot plasma with Langmuir turbulence in a magnetic field

We consider the process of generation of electromagnetic waves as a consequ ence of the merging of two Langmuir plasmons. The case of a hot plasma in a magnetic field is investigated. It is shown that under such conditions the frequency of Langmuir plasmons can vary over the range from 0.8 to 1.1 of the Langmuir frequency of electrons. The spectrum and polarization of elect romagnetic radiation are analyzed. It is shown that allowance for the therm al motion of plasma particles under the conditions involved permits electro magnetic waves in the range from 1.6 to 2.2 of the Langmuir frequency of el ectrons to be generated. The degree of circular polarization of the radiati on can reach 50% even in the case of an isotropic spectrum of Langmuir turb ulence.
