Neutron-proton and neutron-deuteron total cross-sections at 4.0 and 5.7 gev/c

Parker, E.F. ; Gustafson, H.Richard ; Jones, Lawrence W. ; et al.
Phys.Lett.B 31 (1970) 246-249, 1970.
Inspire Record 63208 DOI 10.17182/hepdata.6170

The np and nd total cross sections have been measured directly with a neutron beam with momenta of 4.0 ± 0.6 and 5.7 ± 0.6 GeV/ c . The data are compared with the previous nucleon-nucleon and nucleon-deuteron results, and the deuteron screening term was also evaluated. The measured total cross section are 43.1 ± 0.6 and 80.3 ± 1.9 mb at 4.0 GeV/ c and 42 ± 0.6 and 77.8 ± 1.3 mb at 5.7 GeV/ c .

Neutron-Proton Total Cross-Sections from 40-GeV/c to 280-GeV/c

Longo, Michael J. ; Ayre, Cyril A. ; Gustafson, H.Richard ; et al.
Phys.Rev.Lett. 33 (1974) 725, 1974.
Inspire Record 89896 DOI 10.17182/hepdata.21237

We present results of measurements of the n−p total cross section between 30 and 280 GeV/c. The measurements were carried out with a neutron beam by using the standard transmission technique and a liquid-hydrogen target. A total-absorption calorimeter was used to determine the neutron energy. Our measurements, which have an accuracy of ∼1%, indicate a smooth rise of approximately 1.5 mb between 50 and 280 GeV/c. The combined n−p and p−p data above 20 GeV/c are well fitted by the expression σ=38.4+0.85|ln(s95)|1.47 mb.

Neutron Total Cross-Sections on Nuclei at Fermilab Energies

Ramana Murthy, P.V. ; Ayre, Cyril A. ; Gustafson, H.Richard ; et al.
Nucl.Phys.B 92 (1975) 269-308, 1975.
Inspire Record 2076 DOI 10.17182/hepdata.32056

We have measured total cross sections for neutrons on protons, deuteriom, beryllium, carbon, aluminium, iron, copper, cadmium, tungsten, lead, and uranium for momenta between 30 and 300 GeV/ c . The measurements were carried out in a small-angle neutral beam at Fermilab. Typical accuracy of the data is 0.5 to 1%. The cross sections are consistent with an A 0.77±0.01 dependence over the entire momentum range. The cross sections are compared with theoretical predictions. Agreement is found only if inelastic screening is included. Nuclear radii obtained from our data are in good agreement with previous determinations.
