Towards a More Complete and Accurate Experimental Nuclear Reaction Data Library (EXFOR): International Collaboration Between Nuclear Reaction Data Centres (NRDC)

The International Network of Nuclear Reaction Data Centres (NRDC) coordinated by the IAEA Nuclear Data Section (NDS) is successfully collaborating in the maintenance and development of the EXFOR library. As the scope of published data expands (e.g., to higher energy, to heavier projectile) to meet the needs from the frontier of sciences and applications, it becomes nowadays a hard and challenging task to maintain both completeness and accuracy of the whole EXFOR library. The paper describes evolution of the library with highlights on recent developments.Comment: 4 pages, 2 figure

Activation cross sections of the 169Tm(d,2n) reaction for production of the therapeutic radionuclide 169Yb

Activation cross sections of deuteron induced nuclear reactions on (169)Tm were measured up to 20 MeV by using the stacked-foil technique. Special emphasis was on production of the internal radiotherapy related radionuclide (169)Yb. No earlier experimental cross-section data on deuteron induced reactions on (169)Tm were found in the literature. The experimental data were compared with the results of the nuclear model codes ALICE-IPPE and EMPIRE-II. The integral yield of the (169)Tm(d,2n)(169)Yb reaction was deduced over the optimum energy range Ed = 20-->9 MeV. At 3.8 MBq/microA.h the yield is lower than that available from the commonly used (168)Yb(n,gamma) (169)Yb reactor method but on the other hand, it is higher than the yields from the earlier investigated (169)Tm(p,n)(169)Yb and (nat)Er(alpha,x) (169)Yb reactions
