Thermal Neutron Capture γ's (CapGam)

The energy and photon intensity with uncertainties of gamma rays as seen in thermal-neutron capture are presented in two sets of tables, one in ascending order of gamma energy and a second organized by Z, A of the target. In the energy-ordered table the three strongest transitions are indicated in each case. The nuclide given is the target nucleus in the capture reaction. The gamma energies given are in keV. The gamma intensities given are relative to 100 for the strongest transition. %Iγ (per 100 n-captures) for the strongest transition is given, where known.

All data are taken from Evaluated Nuclear Structure Data File (ENSDF), a computer file of evaluated nuclear structure data and eXperimental Unevaluated Nuclear Data List (XUNDL) both maintained by the National Nuclear Data Center, Brookhaven National Laboratory, on behalf of the U.S. Nuclear Data Program and Nuclear Structure and Decay Data network. The data for A>20 are published in the Nuclear Data Sheets, Elsevier. The data for A≤20 are published in Nuclear Physics A.
