Abstract
In reviewing theoretical and experimental aspects relevant to photo-neutron reactions in gamma ray spectroscopy, this paper limits its considerations to low energies where the reactions proceed through compound nucleus states. Starting with the example of Fe 56 exposed to Bremsstrahlung radiation, the study of cross section and angular distribution relevant to photon-neutron reactions includes a method to determine all possible reaction channels between initial and final states. The review of the principles relevant to experimental techniques deals with how to determine the neutron detector absolute efficiency and sample photon flux in deducing cross-sections from measured neutron spectra. Here, attention is focussed on the problem presented by the random occurrence of start signals in the implementation of time-of- flight measurement.
