Abstract :
Summary form only given, as follows. Investigations of temperature relaxation between electrons and ions and diffusion processes are important problem of plasma physics. The velocity distribution function for the ions in the above-mentioned works has been regarded as isotropic. It is however well known that temperature anisotropy play an important role for the stability properties of confined as well as space plasmas. We considered the processes of temperature relaxation and diffusion under condition in which the parametric excitation of ion cyclotron wave by lower hybrid pump in magnetized plasma with ion-temperature anisotropy takes place. We calculated the diffusion coefficient and the inverse relaxation time in the region above the instability threshold and its dependence on the magnetic field amplitude and ion temperature anisotropy. The results of this report can be of interest for plasma diagnostic purposes.
