Computer study of the dynamics of weak anisotropic Langmuir turbulence

A study is made of the evolution in time of different anisotropic packets of Langmuir waves due to their induced scattering on ions of the plasma. The isotropization of weak Langmuir turbulence is considered in its dependence on the initial data. It is shown that isotropization process may take appreciably longer than the transfer of energy through the spectrum.
