Nuclear Data Nuclear Data is a separate field of study from Nuclear Physics Not research Aim is produce complete, accurate, tested and reliable databases suitable for a range of applications Thus Nuclear Data forms the basis for many other studies
Perceptions Most non-nuclear Data specialists assume that the data exists and are adequate in the same way as a telephone directory exists Data are free Available for all applications particularly new ones If data exist for fission studies then they should also be available for fusion!
Reality Data are not free Require extension and improvement as new applications arise Since measurement usually made relative to a standard, as these improve then original data need to be recalculated Rather few experts International collaboration essential Core role for a body such as IAEA

Nuclear data for Particle Induced Gamma Ray Emission (PIGE) analysis (2011-2014) D. Abriola Objectives: 1 identify the most important nuclear reactions for PIGE; 2 search the literature and electronic databases and convert relevant nuclear reaction data to the format suitable for use in PIGE simulation programs 3 compare data from different sources and carry out measurements when there are no data available or unresolved discrepancies exist; 4 incorporate all measured data into the database, and make them available to the IBA community.

Beta-delayed neutron emission evaluation Sn< Qβ Precursor Sn Important nuclear structure information Pn : β-strength above Sn t1/2(az+1): sensitive to low-lying β-strength
Beta-delayed neutron emission evaluation (20132017) D. Abriola Motivation: Beta-delayed neutrons are important for energy production, astrophysics and nuclear theory Most of the data available are from precursors coming from fission fragments New experimental facilities are available which will be able to produce new precursors in the neutron-rich region Last evaluation with theoretical comparisons is from 2002 There is no database that compiles all relevant data
Beta-delayed neutron emission evaluation Consultant s meeting A related CM was held at IAEA Vienna, 10-12 October, 2011, the consultants pointed out the need of a CRP on the topic
