Abstract
Activation cross sections of deuteron induced reaction on monoisotopic Tm (169Tm) and Pr (141Pr) were measured by stacked foil experiments. First measurements are presented for direct or cumulative production of 141Nd, 140Nd, 139mNd, 142Pr, 139Ce, 137mCe and 140La. Thick target yields and practical batch activity are derived from the fitted excitation curves for the medically relevant 140Nd and 139Pr (as decay product of 139mNd). For reactions on Tm targets previous published results up to 20Â MeV are extended and confirmed up to 40Â MeV for 169Yb, 167,168Tm while high energy values are presented for the first time for 166Yb. Values for the thick target yield (TTY) of 169Yb production are derived and the discussion of different production routes is in agreement with previous published results. A comparison of experimental values with different model codes shows that the upgraded versions of the ALICE and EMPIRE codes can give a better description of (d,pxn) reaction than older ones.
