  1. Evaluator-Reminders 6/07 Jagdish Tuli* National Nuclear Data Center Brookhaven National Laboratory *Email: Tuli@bnl.gov Brookhaven Science Associates

  2. Adopted Properties Q-record – must be given -even if nothing known Values from Audi masses, explanation if from other source, give Audi values for comparison Give Systematic uncertainties as comments. Reminders-Adopted

  3. Adopted Properties XREF even if only one data set with gammas BAND Identification only on first record Reminders-Adopted

  4. Adopted Properties Levels: GS and Isomers: Decay Modes and moments must be given, if known, on the continuation records. Any comments on these should be on the comment records only. T1/2 from keyno. Is not enough, include DSID Moments – Check Stone’s compilation (2005St25) Isomer is a level with T1/2>=0.1 S or if it has an IT dataset Reminders-Adopted

  5. Quote authors’ measured quantities Document any deviations Note authors’ assumptions Check for missed references Check authors’ quoted older values Reminders-extraction of data

  6. Order of Comments E= not needed for reaction Target JPI should be given Keyno: measured, etc. Do not combine different kind of data sets Specify source of data Ensure accuracy of values from adopted set Do not say “from ENSDF” Reminders-presentation of data-1

  7. Gammas order by increasing Eg Significant digits Uncertainty limited to 25 Multiplets Xsection,Analyzing-power not given A2, A4, DCO ratios given with definition Reminders-presentation-2

  8. BEL up for levels, down for gammas. Program modified Delayed gammas - give as IT decay, ex 140Dy Reminders-presentation-3

  9. Normalization condition should be given Parent record, all fields should be given Replace `/’ by `:’ for multiple ratios Unresolved discrepancies should be pointed out Uncertainty not error E(ec),E(b-) only when accurate, measured XUNDL data helpful but evaluator responsibility Reminders-presentation-4

  10. LogT1/2(alpha) vs Log E(alpha) is linear Takahashi’s gross beta decay theory reliable to better than a factor of 3 Alpha Decay HF Certain pairs of conf lead to isomeric transitions GS feeding from local systematics Mass syst from Audi Reminders-Systematics

  11. APS style adopted Accepted abbreviations Key no. is plural. Space after `,’ etc. Reminders-Style
