Table 1: Brief Descriptions of Some of the Data Bases
Data Base Description
CINDA Compiled by members of the NDC network. "Complete" coverage of
neutron-induced reaction references since the discovery of the neutron.
Updated regularly as information is exchanged by the network.
CSISRS Compiled by members of the NDC network. "Complete" compilation
of experimental neutron-induced reaction data with some charged-
particle- and photon-induced reaction data. Updated regularly as
information is exchanged by the network.
ENDF Data from several evaluated nuclear data libraries (ENDF/B-VI,
ENDF/HE-VI, JEF-2, CENDL-2, JENDL-3, and BROND-2) in the
ENDF-5 and ENDF-63 formats. Updated as the libraries are revised.
ENSDF Adopted level and 7-ray information and reaction and decay data for
2,531 nuclides between A = 1 and A = 266. Prepublication versions
of new evaluations are also available. Updated about weekly.
MIRD Nuclear decay data are presented in the Medical Internal Radiation
Dose Format. Extracted from ENSDF and further processed by the
program RADLST4 to obtain Auger- and conversion-electron energies
and intensities and X-ray intensities.
NSR Currently, almost all of low- and medium-energy nuclear physics is
covered. As of mid-July, there were almost 140,000 entries. Coverage
of primary references is essentially complete since 1967 and there are
entries dating back to 1910 in the data base. Updated about weekly.
2.2. Other Data Bases and Information
Other information available from the Center are computer codes, c the Computer
Index to Neutron Data (CINDA),b the Cross Section Information Storage and Re-
trieval System (CSISRS),b data libraries (IRDF-905 and atomic masses6,7), MIRD,"
Physics Codes (PHYSCO - y-ray conversion coefficients and 3 and e log ft's, average
E,'s, and electron-capture fractions.) Q-Value Calculations (QCALC - nuclear reac-
tion Q-values and threshold energies and decay Q-values), Thermal Neutron Capture
Gammas, and XRAY. d Portions of the Online Nuclear Data Service Manual,' ENDF
formats manual,3 and ENSDF formats manual' are also available online.
cThe Center maintains and distributes nuclear structure and reaction analysis, checking, prepro-
cessing, and utility codes on behalf of CSEWG and NSDD. These codes, along with PCNuDat ' and
others, are also available to the general community.
dXRAY calculates attenuation coefficients and total x-ray cross sections for interactions with
elements from H to Fm over the energy range 1 keV to 100 GeV'0 and cross sections for the scattering
of polarized photons from a point or a small finite sized target into a circular detector. t"'
