We have developed a new setup to measure prompt fission $$gamma$$-ray spectra in neutron induced fission up to energies sufficient to reveal the structure associated with giant dipole resonances of fission fragments. The setup consists of multi-wire proportional counters, to detect both fission fragments in coincidence, and two large volume (101.6 mm in diameter and 127.0 mm in length) LaBr$$_{3}$$(Ce) scintillators, to measure the $$gamma$$-rays. The setup was used to obtain the prompt fission $$gamma$$-ray spectrum for thermal neutron induced fission of $$^{235}$$U at the PF1B cold-neutron beam facility of the Institut Laue-Langevin, Grenoble, France. We have successfully measured the $$gamma$$-ray spectrum up to energies of about 20 MeV, what extends the currently known $$gamma$$-ray spectrum limit to higher energies by approximately a factor of two.

By combining neutron activation analysis with multiple $$gamma$$-ray detection, we have proved better sensitivity and resolution for the trace element analysis than the ordinary single $$gamma$$-ray detection method. We now try to apply the multiple $$gamma$$-ray detection method to the prompt $$gamma$$-ray analysis (PGA). We have established a new cold neutron beam line for PGA in Japan Research Reactor, JRR-3M, at Tokai establishment of Japan Atomic Energy Research Institute(JAERI). It consists of a beam shutter, a beam attenuator, a $$gamma$$-ray detector array, a sample changer, and a beam stopper. We construct a high-efficiency $$gamma$$-ray detector array specially designed for this purpose. Its performance has been evaluated with the Monte Carlo simulation code, GEANT 4.5.0.

The Recommended k$$_{0}$$-factors for neutron-induced prompt $$gamma$$-ray analysis and the prompt $$gamma$$-ray emission probabilities

Matsue, Hideaki; Yonezawa, Chushiro

Journal of Radioanalytical and Nuclear Chemistry, 262(1), p.49 - 55, 2004/07

The recommended k$$_{0}$$ factors for 81 $$gamma$$-lines of 24 elements, which are useful for neutron induced prompt $$gamma$$-ray analysis (PGA) and are not influenced by neutron spectrum difference, were obtained from the k$$_{0}$$ factors measured with the cold and thermal guided neutron beams of JRR-3M by statistical calculation. The prompt $$gamma$$-ray emission probabilities were derived from the recommended k$$_{0}$$-factors using atomic weight, isotopic abundance and thermal neutron cross-section of other nuclear constants consisting the k$$_{0}$$ factors, for which one can obtain accurate data. The derived $$gamma$$-ray emission probabilities for the light elements (H to Ca) well agreed within $$pm$$10% with those of the ENSDF, which reflect recent data, which the agreements for heavy elements (Ti to Pb) were $$pm$$40% with those of the ENSDF, which are still composed of old data.
