The efficiency of M021300100014 the neutron detector was found from the comparison M021300100015 of the detected and computed neutron yield from M021300100016 copper. The Li-6 cross section has a peak at about M021300100017 12.5 MeV and its absolute value at the peak is equal M021300100018 to 2.8(0.53) mb. The li-7 cross section has a peak M021300100019 at about 14 MeV and its value at the peak is equal M021300100020 to 3(0.75) mb.
