6. TUNL Review – Dec. 8/9, 2014 TUNL Evaluation Activities 6 We are responsible for nuclear structure evaluation in the A=2-20 mass region Energy Levels of Light Nuclei reviews published in Nucl. Phys. A –Follow style of Fay Ajzenberg-Selove –Broad scope of reactions is included – discussion format. –Adopted levels/gammas, energy level diagrams Evaluated Nuclear Structure Data File (ENSDF) for A=2-20 –More rigorous information required –Better documentation of original sources –Evaluate reaction data sets/decay data sets –Deduce adopted levels/gammas, decay widths, etc. eXperimental Unevaluated Nuclear Data Library (XUNDL) A=2-20 –ENSDF style compilation of current literature Web interface for A=3-20 Information

7. TUNL Review – Dec. 8/9, 2014 ENSDF is the Main Product of the USNDP Structure Group & NSDD 7 Contents: Evaluated experimental nuclear structure and decay data for all known nuclei, organized in over 260 mass A-chains Adopted (best values) Levels: (E, J , T 1/2, , Q, configurations) Gammas: (E , BR, M, , ICC) Decays  -  +  +   - n etc. Reactions (HI,xn  ) (p,p’) (n,  ), (n,xn  ) Coul.
