Thermal-neutron capture cross sections and resonance integrals of the $$^{80}$$Se($$n$$,$$gamma$$)$$^{rm 81m,81g}$$Se reactions

Nakamura, Shoji; Furutaka, Kazuyoshi; Harada, Hideo; Kato, Toshio*

Thermal-neutron capture cross-sections ($$sigma$$$$_{rm 0m,g}$$) and resonance integrals ($$I_{rm 0m,g}$$) leading to ground and isomeric states of $$^{81}$$Se were measured by the activation method. Samples of high purity (99.99%) selenium oxide were irradiated in a rotary specimen rack at the research reactor of Rikkyo University. The irradiation of a cadmium-shielded sample was also conducted to obtain $$I_{rm 0m,g}$$. Wires of Co/Al and Au/Al alloys, which have different sensitivities to neutrons in thermal and epithermal energy regions, were irradiated to monitor thermal neutron fluxes and epithermal components at the same position of one of the rack. A high purity Ge detector was used to measure the $$gamma$$ rays emitted from the irradiated samples and wires, and reaction rates were calculated from $$gamma$$-ray yields. On the basis of Westcott's convention, the cross-sections were obtained as follows: $$sigma_{rm 0,m}$$ = 0.057$$pm$$0.003 b and $$I_{rm 0,m}$$=0.186 $$pm$$ 0.014 b leading to $$^{rm 81m}$$Se, $$sigma_{rm 0,g}$$ = 0.536 $$pm$$ 0.046 b and $$I_{rm 0m,g}$$ = 0.867 $$pm$$ 0.102 b leading to $$^{rm 81g}$$Se.

Cross section of thermal-neutron capture reaction by$$^{99}$$Tc

Furutaka, Kazuyoshi; Harada, Hideo; Nakamura, Shoji; Kato, Toshio; Fujii, Toshiyuki*; Yamana, Hajimu*; Raman, S.*

Journal of Nuclear and Radiochemical Sciences, 6(3), p.283 - 286, 2005/12

Results of a series of study are presented to accurately determine cross section of$$^{99}$$Tc(n,gamma)$$^{100}$$Tc reaction for thermal neutron. An activation method in which $$gamma$$ rays in$$^{100}$$Ru are analyzed, as well as an analysis of ground-state transitions in$$^{100}$$Tc are employed. To reduce uncertainties of the results in an activation method, an attempt was made to determine $$gamma$$-ray emission probabilities accurately. Though accuracies of the results were improved, the uncertainties are still larger than the requested values. Possible improvements are suggested.

Cross Section of Thermal-Neutron Capture Reaction by$$^{99}$$Tc

Furutaka, Kazuyoshi; Harada, Hideo; Nakamura, Shoji; Kato, Toshio; Fujii, Toshiyuki*; Yamana, Hajimu*; Raman, S.*

IST 2005 Abstracts, 2511, p.51, P. 51, 2004/00

In order to experimentally determine cross section of thermal-neutron capture reaction by$$^{99}$$Tc, the following studies have been performed: (1) Measurement of the cross section using an activation method in which $$gamma$$ rays in$$^{100}$$Ru were observed, (2) Measurement of emission probabilities of $$gamma$$ rays in$$^{100}$$Ru, and (3) Measurement of the Cross section from yields of the prompt $$gamma$$ rays emitted in the reaction. In this presentation, details of these studies will be reviewed, and the obtained results will be compared to others. Possible improvements of the experimental methods will also be presented.
