Rules for Evaluation Review Procedure
► The evaluator should produce and send me, two files: the comments which describes the evaluation, The tables which gives the results of the evaluation. If you want a .PDF file in the Monographie format, enter your data with the SAISINUC program, supplied by LNHB, and produce a MS-Access database file called donnees.mdb, send it to LNHB we will return you a Tables.pdf file. ► I will organise a review of the submitted evaluation. An independent reviewer will return you appropriate corrections/suggestions to be made, please take them into consideration and discuss directly with him, just let me inform of the exchange messages. ► When the review process is completed, the reviewer will inform me of his agreement. ► Once these corrections/suggestions have been incorporated into the evaluation and SAISINUC, the evaluator must send updated donnees.mdb and comments.doc files to LNHB. ► We (LNHB member) will read the evaluation before final acceptance and publication on the DDEP website and Monographie.

Completeness of evaluations
Who is using our data ? e.g. the Monte-Carlo simulation codes: we have an interface (Nuc_Pen) between our database and the program “Penelope”. This program “Nuc_Pen”, is a Monte-Carlo code, in which a drawing of lots, weighted by the emission intensity, is done, at each level for each emission (, , , ce, etc.). The sum of the emissions depopulated a level is normalised to 1 A drawing of lot is done. Each emission has a chance to occur which is proportional to its weight g C. E g C. E

Example: Ba-133 Nuc_Pen simulates a decay from the parent nuclide to the ground state level of the daughter in a “cascade of events”.
6
Example : Ba-133 End cascade The overall decay scheme is read, step by step. At the end of one series (called “cascade”) we have a of number of lines. Each line correspond to one emission. 1= electron 2= photon The number of lines corresponding to a given radiation is proportional to its intensity. At the end of the “cascades”, the total number of lines for a certain radiation must be equal to its intensity. This file is used as entry file for the Penelope code

In the database: On paper: Comments: “Similarly, the log ft of the 2nd forbidden decays to the 81- and 161-keV levels are expected to be greater than 10.6 which correspond to branches of less than 0.7% and 0.3%, respectively.”
10
Adjustment of the levels balance
With: Pec(0,1) = 0,1 % and Pec(0,2) = 0,1 % THEN : - What do they require ? Proposal: Put in the database a value which is consistent with the associated level balance, if necessary, with a large uncertainty.
11
Completeness of evaluations
- What is missing ? Moreover, for a good consistency of the calculations, we need: PK + PL + PM + PN + ….. = 1 aK + aL + aM + aN + ….. = aT
