Relativistisch invariante Beschreibung strukturierter Elementarteilchen
Within a dynamic theory of fusion the three-particle-system is examined. Under suitable boundary conditions a method of integra ion is developed, which yields the exact solution of the relativistic three-particle-equation. This solution describes an elementary particle with internal structure. A thorough discussion of the collective motion supplies the massM and spin 1/2 for the new particle and the proper Diracequation, so that an identification of the three-particle-system with the electron is possible.
