Description
Summary:The spectral characteristics of strong Langmuir turbulence in weakly relativistic plasma is analyzed. The temporal evolutions of the turbulence energy density spectra are obtained by perfoyming the fast Fourier transformations on weakly relativistic Zakharov equations. The relativity parameter significantly influenced the Langmuir turbulence, in that a decrease in the relativity parameter lengthened the action time of wave-wave and wave-particle interactions, which is useful for studying the particles acceleration problem.
