APPARATUS AND ANALYSIS FOR SUM-COINCIDENCE (n,$gamma$) SPECTROMETER
Journal Article
·
· Nuclear Instr. & Methods
Apparatus is described for analyzing two-step cascades of neutron capture gamma rays by the sum-coincidence method and consideration is given to the types of results which can be obtained. A detalled analysis is given of detection efficiency and peak shapes and their dependence on the characteristics of the sum discriminator. Several background effects are analyzed quantitatively such as back-scattering between scintlllators, annihilation photon transfer between scintillators, cascades which terminate only near to the ground state, three-photon cascades. and uncertainties caused by unknown angular correlations.
