Abstract：
The experimental data of the neutron total cross section σ_t,nonelastic cross section σ_non and elastic scattering angular distribution σ_el(θ) for ten target nuclei ranging from ¹²C to ²³⁸U with incident energies E_n=20—1000MeV were used to optimize the relativistic phenomenological optical potential (RPOP) through automatic search of the best parameters by computer.In addition,a relativistic microscopic optical potential (RMOP) based on Walecka model were also used to analyze the same data and compare with the RPOP.
Through comparison between these two kinds of relativistic optical potential hints in improving both the RMOP and RPOP is indicated.
