  1. Consistent nuclear model calculations for deuteron induced reactions on Al and Cu FENDL-3 2nd RC M NDS/IAEA, Vienna, 23-26 March 2010 Marilena Avrigeanu and Vlad Avrigeanu • http://tandem.nipne.ro/~vavrig/, http://fp6.cordis.lu/fp6/partners/RCN 49105 "Horia Hulubei" National Institute for Physics and Nuclear Engineering, P.O. Box MG-6, Bucharest, Romania • Motivation • Elastic Scattering (OMP) • Breakup • Pre-equilibrium • Direct reactions • Evaporation • Activation cross sections calculations 2nd RCM-FENDL-3, IAEA Vienna, 23-26 March 2010

  2. IFMIF (International Fusion Material Irradiation Facility) D-Li neutron source for testing fusion reactor candidate materials Motivation: Data Needs • General purpose : Activation/transmutation data library • [U. Fischer: "Nuclear Data Libraries for Advanced Systems: Fusion Devices“, Nov 2007, IAEA, Vienna] • Urgent need for qualified IFMIF reference data library • IEAF/EAF : (n, p, d), to be further developed, improved and validated • Cross section measurements required for neutrons (E >20 MeV): Cr, Co, V, W, Ta, Pb, Bi, Au, Mn deuterons (E < 40 MeV): Cu, Al, Nb protons (E < 12 MeV): Cu, Al, Nb, Ta, W, Au, Pb • Evaluations (n, p, d) to be further developed, improved and validated • Reliable gas production cross-section data (H, He) • Dosimetry data file to be developed for E > 20 MeV (IRDF) 2nd RCM-FENDL-3, IAEA Vienna, 23-26 March 2010

  3. Nuclear Model Calculations • Pure elastic scattering OP analysis SCAT2 [O. Bersillon] - phenomenological OP + semi-microscopic (DF) OP (local version) • DFOLD [M. Avrigeanu] • - double folding method Optical Model Potential M. Avrigeanu et al., P.R.C62 (2000) 017001; N.P.A693 (2001) 616; E.PJ.A12 (2001) 399 ; N.P.A723 (2003) 104; N.P.A 764 (2006) 246. • Direct reactions -breakup FRESCO-2003 [I.J. Thompson] - elastic transfer among weakly bound systems -direct reactions,(d,p), (d,n), (d,t) • Composite system equilibration • STAPRE-H95 [V. Avrigeanu, M. Avrigeanu] (updated) • - OMP:SCAT2000; preequilibrium:GDH / EXCITON;evaporation:Hauser-Feshbach • TALYS - 1.0 [A. Koning, S. Hilaire, M. Duijvestijn] • - OMP:ECIS’97;preequilibrium:MSD / EXCITON;evaporation: Hauser-Feshbach 2nd RCM-FENDL-3, IAEA Vienna, 23-26 March 2010

  4. NO GLOBAL OPTICAL MODEL POTENTIAL (OMP) for d + Nucleus (A<27) • COMPARATIVE ANALYSISofglobal OMPs for d + 27Al, 63,65Cu, 54,56,58Fe, 93Nb: • Lohr-Haeberli (1974): A~40-209, E=8-13 MeV • Perey-Perey (1963,1976): A~40-208, E=12-25 MeV • Daehnick et al. (1980): A~27-238, E=11.8-90 MeV • Bojowald et al. (1988): 27Al, 89Y, 120Sn, and 208Pb at Ed=58.7 and 85 MeV • None of these global OMP describes data at E<15 MeV • Semi-microscopic OMP byusing realistic nucleon-nucleon interaction UDF, & more accurate parameterization for WV, WD, VSO • Phenomenological OMP: parameterization forUR (frozen W&VSO) • Cross-Sections calculations Optical Model Potential 2nd RCM-FENDL-3, IAEA Vienna, 23-26 March 2010
