The following is an Abstract of a paper by H. Aspden at a conference on Quantum Physics held at the University of Gdansk in Poland on 21-25 September 1987.
Abstract: The author's photon theory, which gives a theoretical value of the reciprocal of the fine-structure constant as 137.0359148 for actions in space undisturbed by matter is extended to the material environment. It is shown that effects related to our motion through the cosmic reference frame can account for the part-per-million discrepancies between the above theoretical value and that measured. The photon theory is further supported by a phenomenon connected with resonance effects in an interaction between atomic electrons and the natural oscillations of the space medium, which are at a frequency involving resonant interaction with the gravity field. This concerns the extreme scarcity of the element promethium.
