Summary
In order to calculate the thermal neutron activation cross section of105Ru, the enriched104Ru was exposed to a thermal neutron flux of 1.2·1014 neutrons cm−2s−1. After the decay of the 40-day activity of103Ru, the silver impurity was removed and the contributions from Co and Eu impurities were subtracted. The γ-ray energies and the coincidence results were consistent with the previously established results for106Ru-106Rh. From γ-ray intensities consideration, the thermal neutron activation cross section of105Ru was calculated to be (0.20±.02) barn.
Riassunto
Allo scopo di calcolare per il105Ru la sezione trasversale di attivazione ai neutroni termici, il104Ru arricchito fu esposto ad un flusso di neutroni termici di 1.2·1014 neutroni cm−2s−1. Dopo il decadimento della attività di 40 giorni del103Ru, l’impurità di argento venne rimossa ed i contributi delle impurezze di Co ed Eu vennero sottratte. Le energie dei raggi γ ed i risultati delle coincidenze risultarono in accordo con dati precedentemente raccolti per106Ru-106Rh. Dall’analisi delle intensità dei raggi γ, si è calcolato che per il105Ru la sezione trasversale di attivazione ai neutroni termici è di (0.20±.02) barn.
