The following is a paper jointly authored by H. Aspden and D. M. Eagles and
published in Physics Letters, v. 41A, pp. 423-424 (1972).

### AETHER THEORY AND THE FINE STRUCTURE CONSTANT

**Abstract**: The results of a recomputation of a previously published
theory for the fine structure constant α are presented. A new feature of the
theory is then shown to determine the value of α^{-1} as
108π(8/1843)^{(l/6)} or 137.035915, a figure in agreement with the
observed value of 137.03602±1½ parts per million.

**Commentary**: This paper was jointly-authored with Dr. D. M. Eagles of
the National Standards Laboratory in Australia. The author had been in
correspondence with Dr. Eagles, who took the trouble to check the mathematics
and computation of alpha based on the author's 1969 account [1969b].
The precision of this result inspired this author to suggest the particle space
quantization feature discussed in the paper, which was used extensively in later
work. In spite of the title including the emotive word 'Aether', the paper was
accepted for publication. It was written by Dr. Eagles and submitted from the
National Standards Laboratory with the approval of the Laboratory Director. This
paper was, therefore, a landmark in the charting of events concerning the
development of the author's theory.

13 years later in 1985, B. W. Petley (National Physical Laboratory in U.K.)
in his authoritative work: *'The Fundamental Constants and the Frontier of
Measurement'* referred to the paper using the words:

" No doubt the theoretical attempts to calculate α will continue -
possibly with a Nobel prize winning success. Aspden and Eagles
obtained

α^{-1} = 108π(8/1843)^{1/6}."
