Radioactive contamination and transfer

The ($n, 2n$) cross sections of deuterium and beryllium have been measured for incident neutron energies in the range from 6 to 10 Mev using a large liquid scintillator. The cross sections in barns obtained for deuterium were 0.067\ifmmode\pm\else\textpm\fi{}0.007 at 6.11 Mev, 0.073\ifmmode\pm\else\textpm\fi{}0.007 at 6.55 Mev, 0.088\ifmmode\pm\else\textpm\fi{}0.009 at 7.32 Mev, 0.11\ifmmode\pm\else\textpm\fi{}0.010 at 8.26 Mev, and 0.14\ifmmode\pm\else\textpm\fi{}0.015 at 10.2 Mev. The beryllium cross sections were 0.55\ifmmode\pm\else\textpm\fi{}0.08 at 6.55 Mev, 0.56\ifmmode\pm\else\textpm\fi{}0.07 at 7.32 Mev, and 0.63\ifmmode\pm\else\textpm\fi{}0.09 at 8.26 Mev.
