Copyright, plaigiarism
I notice that you copied some text word-for-word in this edit at least, like "The example we have just given of simplifying the calculation of matrix elements for a dipole transition is really an application of the Wigner-Eckart theorem, which we take up later in these notes" which is copied from Robert Littlejohn lecture notes. There are two problems with this. First, you didn't put the text in quotation marks and cite the source so it's plagiarism. (The source is cited and linked somewhere on the page, but that's not good enough, the copied text itself has to be in quotes with a link right there next to it.) Second, even if you added the source, there would still be a problem: The text is copyrighted by the author (as always), so it's illegal to post it on wikipedia. (If you had quotation marks around the text, it might be OK ("fair use"). But much better to use your own words.)

See Plagiarism for more information. It's no big deal, I'm just letting you know. :-) --Steve (talk) 19:01, 11 August 2015 (UTC)
