摘要:

在800 MeV的标称质子能量下测量了通过质子轰击天然钍靶形成225,227-Ac、223,225-Ra和227-Th的截面。在文献中没有发现通过该方法生产223,225-Ra、227-Ac和227-Th的早期实验截面数据。理论预测与实验数据的比较表明,在两个因素内的协议。结果表明,基于加速剂的225-Ac和223-Ra的生产是可行的生产方法。

英文摘要:

Cross sections for the formation of 225,227-Ac, 223,225-Ra, and 227-Th 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 223,225-Ra, 227-Ac and 227-Th 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 225-Ac and 223-Ra is a viable production method.
