Abstract

Evaluation of 19F(d, xt)18F (β+, T1/2 = 109.7 min) reaction integral cross sections was obtained in the range of deuteron energies Ed = 5—16 МeV. It was obtained in our electronic SaBa (Sarov Base) library using mathematic tools (spline-approximation) of this library. The following cases were the motivation of the research. 19F(d, xt)18F reaction where tritium and 18F nuclei produced in the same amount was used for calibration of the tritium registration efficiency in the measurements of the reaction cross sections of the tritium production by its storage into metal collector. There was a significant contradiction in experimental data. Our new data for 19F(d, xt)18F reaction at Ed = 6.65 and 6.69 MeV and 19F(d, t0) reaction cross section at Ed = 6.99 and 7.99 MeV appeared. We presented the refinement of the published cross sections of tritium production in reactions on lithium isotopes due to acquisition of evaluated 19F(d, xt)18F reaction cross sections.
