When parametric instability is nonlinearly limited in an isotropic plasma, the process of induced scattering of plasma waves by the ions leads to an energy flow into the region of long waves, where there is no Landau damping and energy dissipation can be ensured, say, by decay of the plasma waves. It is shown that in a magnetoactive plasma, induced scattering of the oscillation by the ions can lead to transfer energy into the region of larger wave numbers, where the outflow of energy is ensured by Landau damping by the electrons. Parametric turbulence of a nonisothermal plasma (the electron temperature T/sub e/ exceeds the ion temperature T/sub i/) in a strong magnetic field Vector B/sub 0/ is considered.
