The Zitterbewegung and the Einstein A Coefficient of Spontaneous Emission

  • A. O. Barut


The process of emission and absorption of a photon by the electron is the ultimate basic elementary process of quantum electrodynamics (QED). The QED does not further analyze the details and any possible spatial and temporal structure of this process. Questions concerning the duration of the emission process, the direction of the emission, in fact, the shape of the photon itself, can only be posed and answered in a probabilistic sense and according to the rules of the quantum theory of measurement.
