Abstract
Within the framework of the relaxation time approximation we have comp uted two components of the friction coefficient for various single-par ticle potentials and have found that the nondiagonal component of the friction coefficient depends generally on the diffuseness of the poten tial. The diagonal component of friction, which is related to the two- body dissipation mechanism, was found to be unreasonably large in thes e computations, especially for small temperatures.
