The original Gamma-ray Spectrum Catalogue, Gc(Li) and Si(Li) Spectrometry p
ublished in 1974 by R. L. HEATH has been recreated and enhanced as an elect
ronic file and is available on CD-ROM or over the Internet. This electronic
version includes 1998 gamma-ray data from the Evaluated Nuclear Structure
Data File database as downloaded in 1998 as well as decay scheme drawings.
Future developments of similar catalogues will include gamma-ray spectra fr
om radioactive decay with newer detectors and spectra from neutron interact
ions with elemental samples and separated isotopes. The electronic form of
these catalogues will allow the creation of tutorials on gamma-ray spectrom
etry and on the data included.
