Description

The paper presents a new evaluation of integral cross sections of $\gamma$-quanta production with the energies of 0.429 and 0.478 MeV in the reactions 6Li(d,n1)7Be$^{\ast}$(0.429) (Figure), 6Li(d,p1)7Li$^{\ast}$(0.478), 7Li(d,2n)7Be$^{\ast}$(0.429) and 7Li(d,d1)7Li$^{\ast}$(0.478) obtained with the use of mathematical tools of SaBa [1] electronic library. Uncertainty of evaluated data is in the range of 0.2-11.2%. The reason of the research are the results of our new experiments (random error 5-10%, systematic error 4%) on $\gamma$-quanta registration with HPGe-detector on EGP-10 tandem accelerator of RFNC-VNIIEF at deuteron energies from 2 to 10 MeV with a step of 200 keV. Two LiF targets with thicknesses of 300 mu-g/cm2 (6Li – 70%, 7Li – 30%) and 270 mu-g/cm2 (6Li – 91.06%, 7Li – 8.94%) on thin aluminium and carbon backings were used. Data on the reaction 7Li(d,2n)7Be$^{\ast}$(0.429) were obtained during the measurements of 6,7Li(d,xt) reactions [2] on Li3N with lithium isotope composition 6Li -0.5%, 7Li -99.5%.
This work extends our research [3] on evaluation of 6Li(d,p0,1,2,4) integral cross sections and the corresponding 6Li(d,n0,1,2,4) mirror reactions.
