Neutron-Activation Analysis and the John F. Kennedy Assassination

Kenneth A. Rahn
March 2001

This expanded and refined summary of the NAA data replaces the earlier document of the same name, which will be removed from the web site when this one is made available to the public about 1 March 2001. The new document is still very much a work in progress, however, and should be viewed as such. Also be aware that this document is equivalent to roughly 150200 printed pages, so it will have to be studied with care and over some time, especially by readers not used to dealing with scientific data and ideas. For this I make no apology. The nature of the subject requires it. Comments will be appreciated.
