Subject:

Selection and description of references under REFERENCELEXFOR explains the role of the keyword REFERENCE as follows:“All bibliographic references which contain the preliminary or revised data as wellas information of the specific experiment compiled in EXFOR, i.e., not only thereference from which the data were taken, but also other important references, suchas journal articles, conference papers, and laboratory reports may be coded under
the keyword REFERENCE.”
However, there are entries where the compilers selected some references from thecitation list of the primary article, and added them under REFERENCE without proper
free text explanation. We propose to add the following rule in to LEXFOR:“Only the references checked and analyzed by the compiler can be included under
this keyword. When two or more references are coded, their contents should beindicated in free text”.
If we consider that an Entry represents the information/data reported in the mainreference it would be more appropriate if the free text to an additional referenceindicates how the information/data given in that reference is related to theinformation/data given in the main reference. In this respect the free text
“Experimental details” to the additional references (e.g., Example 2) could besometimes misleading and give the impression that the additional reference contains
experimental details that have not been provided in the main reference. Moreover,regarding the experimental procedure, authors often make reference themselves toother publications if it is appropriate.
Note that we also concluded in the NRDC 2009 meeting that
“A reference in which only the facility or general method is described should be
coded under REL-REF with new code I or M.”

Example 1 (EXFOR 20480.001):
Reference information is given in a short, but informative and correct manner.
REFERENCE(R,CEA-R-4524,197311)
Summarizes some 10 year activity on measurements ofthe total cross-section of many isotopes in theenergy range - hundreds keV to several MeV-.

Example 2 (EXFOR 22820.001):
Reference information is given in incorrect manner.
“A systematic investigation of reaction cross sections and isomer ratios for neutrons
up to 20 MeV on Ni-isotopes and 59Co by measurements with the activation techniqueand new model studies of the underlying reaction mechanisms”, V. Semkova, V.
Avrigeanu, T. Glodariu, A.J. Koning, A.J.M. Plompen, D.L. Smith, S. Sudár, Nucl.
Phys. A730(2004)255
REFERENCE(J,NP/A,730,255,2004) Main reference, data for Ni and Co(R,EUR-20820-EN,2003) Detailed reference, data are given for Ni, Co, Pb, Zr(C,2002SEOUL,,20021007)
Experimental details(J,NSTS,2,(1),192,200208) Experimental details(J,PR/C,65,(1),014604,200201) Experimental details

The details of the experimental procedure applied in the data measurements includedin the Entry 22820 are given in the main reference and none of the additionalreferences contains additional information or has been referred to in the mainreference in respect to the experimental procedure. Following the Example 1 where
the REFERENCE information is given in a concise manner the following presentation
would be more appropriate:
REFERENCE(J,NP/A,730,255,2004)(R,EUR-20820-EN,2003)(C,2002SEOUL,,20021007)(J,NSTS,2,(1),192,200208)

Note that J,PR/C,65,(1),014604,200201 has to be removed. Not relevant to Entry
228020 (“Reaction mechanisms of fast neutrons on 51V below 21 MeV”, P. Reimer, V.
Avrigeanu, A. J. M. Plompen, and S. M. Qaim)
