A Wave Equation for Spin-1/2 Particles: The Dirac Equation,ite probability density. At that time there were doubts concerning the Klein—Gordon equation, which did not yield such probability density [see (1.29)]. The charge density interpretation was not known at that time and would have made little physical sense, because π. and π. mesons as charged spin-0 particles had not yet been discovered.

Projection Operators for Energy and Spin,treatment of complicated expressions; especially the calculation of traces of products of many γ matrices. It is based on a ., i.e. a method to project a spinor with a given sign of energy and fixed polarization out of a general wave function or a wave packet. The appropriate operators which achieve this are called ..

Wave Packets of Plane Dirac Waves,f the free solutions, we study wave packets. These are superpositions of plane waves which yield localized wave functions in space time. Since the Dirac equation is a linear wave equation, the wave packets are also solutions of the free Dirac equation, which is just the superposition principle.

,The Foldy—Wouthuysen Representation for Free Particles, to positive (negative) energy states, the upper (lower) two components beecome large compared to the lower (uppeer) two components [cf. (2.44), (2.72)]. The question arises, whether there exists a representation that reflects this property as a general feature, i.e. also for large velocities of the particles.
