摘要：

Cross sections for the formation of Ac-225,Ac-227, Ra-223,Ra-225, and Th-227 via the proton bombardment of natural thorium targets were measured at a nominal proton energy of 800 MeV. No earlier experimental cross section data for the production of Ra-223,Ra-225, Ac-227 and Th-227 by this method were found in the literature. A comparison of theoretical predictions with the experimental data shows agreement within a factor of two. Results indicate that accelerator-based production of Ac-225 and Ra-223 is a viable production method. Published by Elsevier Ltd.
