The following is a paper by H. Aspden published in Lettere al Nuovo Cimento, v. 38, 342-344 (1983).
Abstract: A recently reported resonant-cavity model of the muon is now shown to have an additional resonance mode involving wave propagation around the muon core charge. This resonance gives a slightly modified value of the muon-electron mass ratio and uniquely determines it as 206.7683078, in excellent accord with its latest experimental value 206.768 35(11).
Commentary: By this stage the author well knew that his aether theory could give extremely precise account of the nature of the most fundamental particles. He realized that their properties were only measured to such very high precision to provide the basis for testing new theory, but yet that his was the only viable theory that could give the right answers.
It became a challenge to decipher the form of the simple resonance that could account for the minor residual discrepancies one would expect as due to background energy noise in a physical environment. There had to be such resonances occurring naturally in order to explain why the measurements could be so consistent and definite. This challenge drove the author forward and the author had in mind the magnetic moment properties of the proton, the neutron and the deuteron. However, several other papers were to come before complete success could be reported on all those specific topics. Yet, the author had, whilst listening to a speaker describe neutron measurements at the 1981 Gaithersburg National Bureau of Standards conference, registered in his mind the governing resonance applicable to the neutron, and a full picture was already evolving at that time.
