| Abstract | Summary. Irradiation of nitrogen with protons leads to 11C (T1/2 = 20.4 min) via the well-known 14N(p, α) reaction. How-ever, 14O (T1/2 = 70.6 s) and 13N (T1/2 = 10 min) are also formed as side products via the 14N(p, n) and 14N(p, d + pn) reactions, respectively. In this work detailed cross section measurements were carried out for those two side reactions up to 19.2 MeV using N2 gas and nitrogen-containing solid targets. From the data, the thick-target yields and the exact level of radioactive impurities in 11C were calculated. In the case of 14O, the results also confirmed the possibility of producing this β+ emitting radionuclide in sufficient quantities for PET investigations. 1. |
