I found Gustave Le Bon's missing book called "Synthetic Radioactivity"!

[gravityblock]

It appears the book called or known as "synthetic radioactivity" is actually the book titled, "The Evolution of Matter".  According to the History Timeline of 1940-1947 (link is no longer valid), the book which was withdrawn and confiscated from the libraries was the book titled "The Evolution of Matter", while Synthetic Radiation is in Parenthesis next to it and without the quotation marks.  In Pentagon Aliens, by William Lyne, it says on page 167, "Gustave Le Bon wrote a book on synthetic radioactivity".  It doesn't say the book is titled "synthetic radioactivity", but instead says the book is on, or in other-words, about synthetic radioactivity.  Another possible explanation could be the term "synthetic radioactivity" was an alias for this book during that time since it was on the FBI's retrieval list.   Please take notice of the footnote #16 above "synthetic radioactivity" in Lyne's book.  Footnote #16 says, "Gustave Le Bon, The Evolution of Matter, publisher unknown [ca. 1890]".  The first image below, is a snapshot taken from the page on the Timeline.  The second image, is taken from page 167 of "Pentagon Aliens".

Hej Gravoc,

Please check your links because they got corrupted when you copied them and do not work. (I mean the last two links)

In a case of unavailability, I'm ready to upload both of them at my Rapidshare account; I'm in possession of both of them, in pdf format.

Both download links for "The Evolution of Matter" and "The Evolution of Forces" have been corrected in the original post.  Thanks for bringing this to my attention.
