I'll fax you the neutron spectra from: "COMPENDIUM OF NEUTRON SPECTRA AND DETECTOR RESPONSES FOR RADIATION PROTECTION PURPOSES," Griffith, Palfalvi, and Madhvanath, IAEA TRS No.318, 1990. It's an excellent resource, but then again, I'm partial since I worked with Palfalvi while in Budapest. Jeff Chapman ORNL 423-574-5729
