FENDL-3 1st Research Co-ordination Meeting, 2-5 December 2008, IAEA, Vienna17 Marilena Avrigeanu CONCLUSIONS  Starting point: available (d,d) and  R data for d+ 27 Al, 54,56,58,nat Fe, 63,65,nat Cu, 93 Nb  poor description by global OMP parameter sets  Semi-microscopic OMP analysis  U DF : ρ d (charge) & ρ Al (charge) & M3Y Paris-NN  W D & V SO phenomenological  improved agreement with data adding the dispersion corrections  Phenomenological OMP analysis for 27 Al  agreement with all available measured data  good description of (d,d) data vs. TALYS default OMPs  improved description of (d,d) data vs. global OMPs  Completion of d+ 27 Al activation cross sections  Deuteron break-up mechanism contribution taken into account  DR mechanism considered trough n & p stripping contributions  Comparison of STAPRE-H / TALYS-1 activation cross sections  NEED to UPDATE the d-activation libraries
