摘要: Differential cross sections for elastic scattering of neutrons from /sup 54,56/Fe have been measured at several energies in the 20--26 MeV region. The data analyzed both terms standard phenomenological optical model, and framework two different microscopic models based upon nuclear matter calculations using realistic nucleon-nucleon interactions a local density approximation. Isospin consistency microscopic-model was also tested by analyzing proton differential section same energy region, as well neutron power data. yield quite reasonable agreement with data, even though they contain no free geometrical parameters. quality results is particularly impressive, indicating that very simple, density- energy-independent spin-orbit force used sufficient. differences between various are clarified examining momentum-space representations potentials.
