Reference Input Parameter Library (RIPL-2) • library of parameters for theoretical calculations of nuclear reactions • based on starter file RIPL-1 (released 1997) which was tested, validated and extended • for incident and outgoing particles: n, p, d, t, 3 He,  ,  up to ~100 MeV • data on web at http://www-nds.iaea.org/RIPL-2/ • handbook (IAEA-TECDOC-1506, August 2006) and CD-ROM versions << 1/4 International Atomic Energy Agency

Reference Input Parameter Library (RIPL-3) • Extend RIPL-2 database - for nuclear model calculations up to 200 MeV as required for emerging applications such as ADS & others • Develop routines for calculation of certain input parameters to facilitate access of users to RIPL library and prevent misuse of parameters • Improve quality of data by using new experimental results and microscopic approaches to derive parameters << 2/4 International Atomic Energy Agency

Nuclear Data for Ion Beam Analysis (IBANDL) IBA techniques exploit the interactions of rapid (from ~0.1 to a few MeV) charged particles with matter to determine the composition and structure of the surface regions of solids (from ~0 to 100 m m). Compositions and structures are inferred from measured quantities such as charged-particle, gamma-ray and x-ray spectra, or excitation curves, via physical models incorporating the sample structure and the basic physical processes and quantities giving rise to the observed spectra or excitation curves. The basic physical processes underlying IBA are well understood, but the reliability of data interpretation is limited by knowledge of the physical data. << 1/2 International Atomic Energy Agency
