† Uranium atoms undergo fission to produce fast neutrons with energies 100 keV to 10 MeV. Moderation produces thermal neutrons with an average energy of 0.025 eV. Moderation at low temperature produces cold neutrons with energies < 0.25 eV. RickL. Paul earned a B.S. in chemistry from Western Illinois University and a Ph.D. from Purdue University, where his research interests included neutron activation analysis of meteorites. He was a postdoctoral research associate at San Jose State University before coming to the National Institute of Standards and Technology in 1991. His current areas of research include cold neutron prompt gamma-ray activation analysis as well as radiochemical neutron activation analysis. He is an author of over 30 papers on PGAA.

“…Methods for determining suites of elements by epithermal neutron activation analysis were developed by Parry (100) and Rosenberg et al (101). Neutron-capture prompt 7-ray activation analysis (PGAA) is finding use as an analytical technique that can account for ~99% of the mass of small samples (102,103). An absolute method for analyzing trace elements in single grains was developed by Watterson et al (104) as a complementary technique for scanning electron microscope and electron microprobe analysis of major and minor elements.…”
