A model for a self propelling photon — •Karl Otto Greulich — Fritz Lipmann Institut Beutenbergstr 11 07745 Jena

Theoretical descriptions which rely on a point like photon neither give information on the birth (emission from a single atom or molecule) of a photon nor on why a photon, after its emission, in vacuum perpetually moves with speed c. Since in addition, inspection of experimental details has raised some doubts whether the photon's particle character is unequivocally proven, alternative photon models with some spatial extension can no longer be discarded a priori. Here a model is given where two clouds of Planck charges (e/SQRT alpha where alpha is the fine structure constant, see also G30 and T280 of the Göttingen meeting) oscillate between a state of capacitor like separation and a ring current. This model explains to some extent why light is a transversal electromagnetic wave and why, once started, moves in vacuum with speed c. Also it gives the spin of the photon as 1 and its spatial extension as wavelength / 2 pi. References: K. O. Greulich Int. J. Mol Sci (2010), 11, 304-311; K.O.
