The experimental and evaluated information stored in the numerical databases, such as EXFOR and ENSDF, have been compiled on the basis of the result of experiments and reviews published in a variety of scientific journals and reports. The bibliographic databases contain cross references between the information stored in the numerical databases and the original articles on which these data are based.
CINDA, the Computer Index of Neutron Data, contains bibliographical references to measurements, calculations, reviews and evaluations of neutron cross-section and other microscopic neutron data. It includes also references to computer libraries of numerical neutron data available from the Neutron Reaction Data Centres network, such as the EXFOR database.
The scope of CINDA is limited to publications giving information about nuclear reactions initiated by a neutron-nucleus collision. Primarily this includes neutron scattering, neutron capture, fission, and other reactions producing charged particles or neutrons, but a few other categories of information of interest to reactor physicists have been included: scattering of neutrons by bound atoms, some photon-induced reactions, and spontaneous fission.
Each entry in the CINDA database comprises of one line of textual information in a fixed column format. It identifies the nuclide, reaction, the type of data, and the source of the data, together with a free text comment where one or two of the most important features of the work can be indicated. Where information on a given data set has been published in more than once place, the corresponding CINDA entries are blocked together to show that a correlation exists between them.
A number of codes are used in the CINDA entry - for example, to describe the reaction type, energy or laboratory. In some cases (laboratory) the code used is common to both the CINDA and EXFOR systems. A list of the fields in each CINDA entry, linked to further information within the CINDA manual where appropriate, is given below.
The CINDA format has recently been updated and cover now neutron as well as charged-particle data.
The complete (old) CINDA manual is in three parts:
|Section I||General summary 25KB|
|Section II||Detailed specifications and instructions|
Online access provides an easy way to make searches of the CINDA database. To specify a nuclide, enter its Chemical Symbol
or Z number and the Atomic Mass (A) or Compound fields.
The reaction is specified by selecting values from the scrolling lists.
Other fields allow additional parameters, such as lab code, energy, reference, or author name, to be added to the search criteria.
The Nuclear Science References (NSR) file is a bibliographic database covering low- and intermediate-energy nuclear physics. The NSR file originate during the mid-sixties at the Nuclear Data Project (NDP) at Oak Ridge National Laboratory as a part of a program of systematic evaluation of nuclear structure data. The NSR file contains references to published and unpublished work relevant to nuclear structure. At the same time the NDP created the Evaluated Nuclear Structure Data File (ENSDF) containing the physical data.
The NSR file contains references for papers that report experimental data on nuclear structure, radioactive decay and nuclear reactions and on theoretical studies of specific nuclei and nuclear reactions.
About 80 journals from various parts of the world are scanned for information fulfilling the inclusion criteria. These are the primary references. In addition, relevant information from secondary references such as laboratory reports, conference proceedings, theses etc. is also coded.
A full and detailed description of the NSR format is provided on the Nuclear Science References help page.
The NSR database is maintained at the NNDC Nuclear Data Centre.
