Total neutron cross sections en deuterium in the energy range 1 keV to 1000 keV have been measured, and basically agree with our previously reported results. Total neutron cross sections on deuterium provi de a basic test for nuclear three body theory. The most recent continuous energy Measurement in the MeV region was repcrted by Clement et all. These measurements covered the neutron energy range 0.5 MeV to 30 MeV. The only extensive measurements below 0.5 MeV were recently reported by the present authors. They found a rapid rise in cross section for decreasing 2 neutron energy below 300 keV. The experimental results were well explained by three body theoretical calculations of the quartet n-D scattering. The present communication reports a remeasurement of the total cross section below 1.0 MeV, under somewhat difiereiit experimental conditions, V NOTICE | This report was prepared as an account of workl sponsored by the United States Government Neither I MASTER the United States nor the United States Atomic Energy
