Total cross sections of 19F(d, xt)18F (β+, T1/2 =109.7 min) reaction are evaluated in the range of deuteron energies Ed = 5–16 МeV in our electronic SaBa (Sarov Base) library using mathematic tools (spline approximation) of this library. The reasons for the research were the following. The reaction 19F(d, xt)18F where tritium and 18F nuclei are produced in the same amount has been used for calibration of the tritium detection efficiency in the measurements of cross sections of tritium-producing reactions by the method of tritium accumulation into metal collectors. 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.
