Li6andLi7(n,2n)Cross Sections

Absolute measurements of the 10.2- and 14.1-MeV ($n,2n$) cross sections of ${\mathrm{Li}}^6$ and ${\mathrm{Li}}^7$ have been made using the large scintillator technique. The cross sections in barns obtained for ${\mathrm{Li}}^6$ are: 0.033±0.015 at 10.2 MeV and 0.070±0.006 at 14.1 MeV. The ${\mathrm{Li}}^7$ cross sections are: 0.027±0.015 at 10.2 MeV and 0.056±0.005 at 14.1 MeV.
