Production Cross Sections for (n,t) Reactions in Some Medium and Heavy Mass Nuclei at 14.6 MeV

The cross section for (n, t) reaction of 14.6 MeV neutrons with isotopes of the natural elements calcium, iron, yittrium, and lanthanum, and with enriched isotopes strontium-86, calcium-114, tellurium-130, and thallium-205 were measured by the activation technique using high-energy resolution gamma-ray spectrometry. The experimentally determined values of the cross sections are in good agreement with values calculated by an empirical equation. The cross section ratios of (n,t) and (n,p) reactions were calculated on the basis of the statistical model.
