Studying the excitation function of the full cross section of a reaction using a modified transmission technique: Initial results

A method for direct and model-independent measurements of the full cross section for the reaction σ R is described, along with the physical setting and the results from measuring σ R ( E ) for the reaction 6 He+ 197 Au in the energy region near the Coulomb barrier. A comparison of cross section valu...

Description
Summary:A method for direct and model-independent measurements of the full cross section for the reaction σ R is described, along with the physical setting and the results from measuring σ R ( E ) for the reaction 6 He+ 197 Au in the energy region near the Coulomb barrier. A comparison of cross section values measured by the direct method with a summed cross section of the reaction’s xn evaporation channels ( x = 2–7) and a neutron’s disruption-pickup channels measured by means of activation analysis is presented, along with the familiar value in the literature for a full cross section obtained from processing with an optical model of experimental differential cross sections of the elastic scattering of 6 He on 197 Au.
