We investigate the Dirac equation in the semiclassical limit \hbar --> 0. Asemiclassical propagator and a trace formula are derived and are shown to bedetermined by the classical orbits of a relativistic point particle. Inaddition, two phase factors enter, one of which can be calculated from theThomas precession of a classical spin transported along the particle orbits.For the second factor we provide an interpretation in terms of dynamical andgeometric phases.Comment: 8 pages, no figure
