MEASUREMENT OF CROSS SECTION OF (n,2n) REACTION BY 14 Mev NEUTRONS WITH Be, Pb, AND Bi (in Russian)

Journal Article · · Atomnaya Energ.
OSTI ID:4272619
The graphite prism, in a previously described fact neutron detector was used for measuring the (n,2n) reaction cross sections for beryllium, lead, and bismuth. The detector had a constant sensitivity at neutron energies 0.1 to 8 Mev and somewhat lower sensitivity to 14-Mev neutrons. The cross sections were determinod In relation to the detector recording rate with and without specimens of the material studied. The total cross section for metallic beryllium specimens of 2.99 cm diameter and 0.583, l.778, and 2.695 cm thickness was sigma /sub t/ = (1.42 plus or minus 0.02) barns. The (n,2n) reaction cross sections with Be, Pb, and Bi were 0.55 plus or minus O.O6, 2.30 plus or minus 0.18, and 2.42 plus or minus 0.20 barns, respectively. (R.V.J.)
