The calculation is given on page 8 of the Powerpoint (attached below) of my talk at the recent Vigier XI conference in Liege, Belgium. The derivation is also given on p 10-11 of my double-helix photon model article at <a href="https://richardgauthier.academia.edu/research#papers" class="">https://richardgauthier.academia.edu/research#papers</a> , which is attached below for your convenience.</div><div> Richard</div><div></div></body></html>
