文摘

Extension up to 50 MeV incident deuteron energy is presented for excitation functions of activation products formed in monoisotopic Tm (¹⁶⁹Tm) and Pr (¹⁴¹Pr). By stacked foil irradiations direct and/or cumulative production of ^140,139m,138Nd, ^138mPr, ^{141,139,137m,135}Ce on Pr and ^166,169Yb, ^166,167,168Tm on Tm targets were measured. Confirmation of earlier experimental results for all investigated radionuclides is found and the influence of the higher energy on thick target yields and batch production of medically relevant radionuclides (¹⁴⁰Nd, ¹³⁹Pr (as decay product of ^139mNd), ^166,169Yb, ¹⁶⁷Tm) is discussed. A comparison of experimental values with TALYS1.6 code results (predicted values from TENDL-2015 on-line library) shows a better description of the (d,pxn) reactions than older ones.
