MEASURED AND CALCULATED RADIONUCLIDE PRODUCTION FROM COPPER, GOLD, AND LEAD SPALLATION TARGETS

In order to verify the production rates of radionuclides calculated by the Los Alamos High Energy Transport code (LAHET), a series of experi ments were conducted using the Texas A&M University Cyclotron to measu re radionuclide yields from copper, gold, and lead targets bombarded b y 120 MeV deuterons. The measured yields were compared to a set of cal culated yields generated from LAHET simulations. Several irradiation t imes and decay times were used to improve sensitivity to both short-li ved and long-lived nuclides. Agreement between the measured and calcul ated radionuclide yields was found to be generally within a factor of two. (C) 1998 Elsevier Science B.V. All rights reserved.
