Abstract
A model Fokker-Planck kinetic equation is postulated which describes c oupled spin-velocity relaxation of test particles immersed in a buffer gas. The proposed model accounts for specific parts of the friction f orce ('Magnus'-type and 'sailing'-type) to which a spinning test parti cle is subjected. Special attention is paid to the 'Magnus phenomenon' in the case of spin-half particles. Some curious thermodynamic aspect s are discussed.
