Fast neutron scattering cross sections at small angles and optical model parameters
- 1. Department of Modern Applied Physics, Tsinghua University, Beijing, 100084 (China)
Description
A position sensitive neutron detector was used to measure the differential cross sections of 14.8 MeV (or 14.7 MeV) neutrons scattered from 238U, Pb, Ni, Fe, Cr, Al, and O between 2.5 degree and 16 degree and that of 12 MeV neutrons from 238U and Fe. The data were corrected for neutron flux attenuation, multiple neutron scattering, and finite geometry with a Monte Carlo simulation. The angular distributions are analyzed with a spherical optical model or coupled channels model (code ECIS79) and a set of global optical model parameters were obtained at ∼14.8 MeV neutron energy for mass number between 27 and 238. The measured and calculated results are compared and discussed
