Measurement, With a Free Neutron Beam, of Absolute Neutron - Proton Forward Elastic Scattering Differential Cross-section at Intermediate-energies

Terrien, Y. ; Lugol, J.C. ; Saudinos, J. ; et al.

The differential cross section in free n-p forward elastic scattering has been measured for incident neutron energies of 378, 481, 582, 683, 784, 884, and 1085 MeV and for momentum transfer 0.01<‖t‖<0.08 (GeV/c)2. The experiment used a recoil-detector ionization chamber which served at the same time as a gas target. Special care has been taken to obtain a precise absolute normalization.

Experimental Evidence for Structures in the Momentum Dependence of the n + p --> p + n Charge-Exchange Peak Between 1-GeV/c and 2-GeV/c

Bizard, G. ; Bonthonneau, F. ; Laville, J.L. ; et al.
Nucl.Phys.B 85 (1975) 14-30, 1975.
Inspire Record 615 DOI 10.17182/hepdata.7809

21 differential cross section measurements of the np → pn charge-exchange reaction have been carried out at the synchrotron Saturne (Saclay), for incident neutron momenta between 1 and 2 GeV/ c and in the squared four-momentum transfer range 0 ⩽ −t ⩽ 0.4 (GeV/ c ) 2 . The π exchange peak is seen at all the incident momenta. The s dependence of the very forward slope of this peak shows weak structures near the threshold of inelastic channels.
