Hi, I have placed an updated Word document on my web site, that now also includes a non-relativistic derivation, which is much easier to follow. The document is best viewed using Word, in "page layout" mode. (Other modes tend to produce a mess).
The document can be found at: http://rvanspaa.freehostia.com/theory.zip Regards, Robin van Spaandonk <[email protected]>
