Abstract

The magnetized kinetic equation derived earlier (Hassan and Watson (1977)) is used to study the problem of relaxation of anisotropic electron and ion temperatures in a magnetized plasma. The case of anisotropic electron temperature relaxation for small anisotropies the exchange of energy within the electrons between the components parallel and perpendicular to the magnetic field direction determine the relaxation rate. For anisotropic ion temperature relaxation the essential mechanism for relaxation is provided by energy transfer between ions and electrons, and the expression for the relaxation rate perpendicular to the magnetic field contains a significant term proportional to In eta 0 ln (me/mi) (where eta 0= Omega e/kDVe perpendicular to ), in addition to the term proportional to the Coulomb logarithm.
