摘要：

Results of the total cross section difference Delta sigma(L) in a np transmission experiment at 1.19, 2.49 and 3.65 GeV incident neutron beam kinetic energies are presented. Measurements were performed at the Synchrophasotron of the Laboratory of High Energies of the Joint Institute for Nuclear Research in Dubna. Results were obtained with a polarized beam of free quasi-monochromatic neutrons passing through the new Dubna frozen spin proton target. The beam and target polarizations were oriented longitudinally. The present results were obtained at the highest energies of free polarized neutrons that can be reached at present. They extend the energy range of existing results from PSI, LAMPF and Saclay measured between 0.066 and 1.10 GeV. The new results are compared with Delta sigma(L)(pn) data determined as a difference between Delta sigma(L)(pd) and Delta sigma L(L)(pp) ANL-ZGS measurements. The values of Delta sigma(L) for the isospin state I = 0 were deduced using known pp data.
