Savannah River Laboratory, Aiken, South Carolina, through the Argonne Code Center, Argonne,
4. HISTORICAL BACKGROUND AND INFORMATION
Since the first Catalogue of Gamma-Rays Emitted by Radionuclides was published by M. A. Wakat
in 1971, the continued use of Ge(Li) detectors of high resolution has resulted in a general upgrading
of nuclear decay data. The present work consists of data from the original catalogue card files with
additions and corrections where newer, superior data were at hand.
5. APPLICATION OF THE DATA
Because of the increased precision of the revised data, several minor policy changes were made
to allow for: 1) Energy listings to 0.01 keV, where available; 2) Uncertainty listings for the energy,
where available; 3) Use of exponential notation for half-lives and gamma-ray abundances; 4) Revision
of the production mode code; 5) Listing the two most-abundant associated gamma rays to the nearest
6. SOURCE AND SCOPE OF DATA
GAMTAB has a separate table of the data listed by nuclide. By means of the original Catalogue,
the source of a gamma ray could be narrowed initially via two associated gamma rays to several
possibilities. However, to reduce these possibilities to one, much further searching through the
Catalogue and spectrum was required. In this work, TABLE II, the listing by nuclide of up to 50
associated gammas, will allow a more rapid and thorough search of the data for each of the possible
nuclides and eliminate the less abundant gamma rays from further scrutiny.
