XXXVIII. The hydrogen and carbon total cross-sections for neutron energies between<i>39</i>MeV. and<i>156</i>MeV.

Abstract

Abstract The total cross-sections of carbon and hydrogen have been measured at neutron energies of 39, 64·5 and 97 MeV., using a recoil proton telescope as a neutron detector. At these three energies the hydrogen cross-sections are 223±7·6, 126±3 and 73·9±3·0 × 10 -27 cm.2 respectively. The corresponding carbon cross-sections are 1100±20, 784 ±5 and 508±5 × 10-27 cm.2.
