“…89, 204 (1953). 2 The neutron flux attenuated lengthwise through this cylinder was compared with the direct flux transmitted through an identical, evacuated cylinder, the hydrogen transmission being about 0.57. The length of the cylinder was known to 0.01% and the hydrogen pressure was measured to 0.1%.…”

“…Preliminary results of this work were published some time ago. 2 Nearly all previous experiments were complicated somewhat by the fact that the hydrogen total cross section was deduced from the difference between the cross sections for a hydrocarbon and carbon. Here, however, the hydrogen cross section a was obtained from the transmission T of hydrogen gas for 20-Mev neutrons by means of the usual relation where n is the density of hydrogen nuclei and / is the length of the scattering volume.…”

The total scattering cross section for neutrons incident on protons has been measured in a good-geometry transmission experiment. The scatterer was hydrogen gas contained in a pressure vessel one meter long, at a pressure of 4000 psi. The resulting cross section is o-*=0.4942±0.0025 barn at a laboratory neutron energy of 19.665±0.026 Mev. 3 The transmission cell was designed and tested in 1951 by Mills, Edeskuty, and Sesonsky of this Laboratory, at the request of J. H. Coon. A description of the cell appears in J. D. Seagrave and R. L. Henkel, Phys. Rev. 98, 666 (1955), Appendix I. 4 Coon, Bondelid, and Phillips [quoted in Coon, Graves, and Barschall, Phys. Rev. 88, 562 (1952)] used the same cell for an accurate hydrogen total cross-section measurement at 14 Mev. 209
