1. 2nd meeting of IAEA CRP on FENDL-3 23-26 March 2010 Proton and deuteron activation cross section data for FENDL-3Progress reporton experiments and data evaluations made by the ATOMKI Group2009-2010Activation cross section data for deuteron induced reactions F. Tarkanyi, B. Kiraly Institute of Nuclear Research of the Hungarian Academy of Sciences

2. Proton induced reactions • Motivation: activation calculations for IFMIF • First library in EAF-2007 • Generated by TALYS model code • At this stage no improvements or renormalizations • Only a start, requires: • Uncertainty data • Improvements • Validation

3. Compilation of proton induced data • Compilation of proton induced activation cross sections were started up to 100 MeV • In the first stage only the EXFOR database was used • Targets: Ag, Al, C, Co, Cr, Cu, Fe, Li, Mn, Mo, N, Nb, Ni, O, P, S, Sb, Si, Sn, Ta, Ti, V, W • The number of reactions is around 400 • The preparation of the list of the missing, duplicated and wrong EXFOR entries is in progress

5. Deuteron induced reactions • Preliminary library in EAF-2005.1 • Used for calculations of impurities in Li target • Generated by TALYS model code • Improved for EAF-2007 by use of: • Additional data sources • Renormalization of some reactions to EXFOR • Only a start, requires: • Uncertainty data • Improvements • Validation • Motivation: activation calculations for IFMIF

6. Compilation of deuteron induced data • Deuteron activation cross sections were compiled up to 50 MeV • In addition to the EXFOR database, some other important reference sources should be checked (e.g. Nuclear Science References, NNDC, Brookhaven National Laboratory and Landolt-Bornstein books) • The number of reactions is above 400 • Targets: Ag, Al, C, Co, Cr, Cu, Fe, Li, Mn, Mo, N, Nb, Ni, O, P, S, Sb, Si, Sn, Ta, Ti, V, W • Additional targets were included: Au, Cd, In, Ir, Mg, Pb, Pd, Pt, Rh, Y, Zn, Zr • The preparation of the list of the missing, duplicated and wrong EXFOR entries is in progress

7. Deuteron induced reactions

8. Status of the experimental database • The experimental database is relatively poor • Mostly elemental cross sections • Independent and cumulative data • Mostly low energy data due to the limited applications and the limited accelerators available • Only a few groups have reported higher energy data (JAEA, ATOMKI) • Series of new unpublished experimental data from ATOMKI (collaborations with VUB, CYRIC, IPPE)

9. New CRP related unpublished experimental data from ATOMKI

10. Conclusions from the compilation and evaluation of the experimental data • The number of the reactions is so large (~400 deuteron and ~400 proton) that the critical evaluation of the experimental data (reading all original papers) will have some limitations • There are numerous results not converted to EXFOR • There are many very disturbing mistakes in the compiled EXFOR entries • Limited information in the original publications • No possibility to correct for nonlinear parameters

11. Comparison with the theoretical models and data libraries • Comparison with the TENDL-2009 for all reactions • Comparison with the EAF-2007 for the most important targets • Comparison for selected cases with EMPIRE-D and ALICE-IPPE D

12. Conclusions from the comparison • Large discrepancies with TENDL-2009 • Missing calculations in TENDL- 2009 • The “adjusted” data of EAF-2007 in some cases are better but still not satisfactory (only about 20-30% is acceptable) • Very surprising the large differences in the shape of the “blind” TENDL-2009 and EAF-2007 • Poor results in case of (d,p) and (d,t) reactions • Reasonable agreements with ALICE-IPPE for the “total” production • Good reproduction of (d,p) and (d,t) in ALICE-D and EMPIRE-D • Without fitting to the experimental data the predictions are poor!!!

13. Format • MS EXCEL is used to collect experimental and theoretical data, to make the necessary corrections or normalizations and to create graphs • Only the final results will be transformed to ENDF format

20. Future plans / Deuteron • Comparison of the experimental data with results of EAF-2007 for all deuteron induced reactions (time consuming due to the missing summarization of contributing reaction channels in EAF!!!) • De-selection of the contradictory data taking into account the experimental circumstances • Comparison of the experimental data also with the available ALICE-IPPE and EMPIRE-II calculations for reactions measured by the ATOMKI Group • To make available for FENDL-3 all experimental data recently measured by ATOMKI (publications) • New experimental data for missing important reactions

21. Future plans / Protons • Continuation of the evaluation of the proton induced cross section data • Extension of the compilation with the experimental data found using the secondary reference sources (e.g. Nuclear Science References, NNDC, Brookhaven National Laboratory and Landolt-Bornstein books) • De-selection of the contradictory data taking into account the experimental circumstances • Comparison of the experimental data also with the PADF and JENDL, available ALICE-IPPE and EMPIRE-II calculations for reactions measured by the ATOMKI Group • New experimental data for missing important reactions
