Measurement of Neutron Radiative Capture Cross Section for 56Fe（n,γ）57Fe Reaction From 9.0 to 20.0 MeV

摘要

正 Neutron radiative capture cross sections of 56Fe（n,γ）57Fe reaction have beenmeasured in two incident energy ranges,from 9.3 to 16.0 MeV at 90° and from 9.0 to20.0 MeV at 55° and 125°.Time-of-flight technique is used to discriminate neutronsand gamma rays.The asymmetry of fore and aft γ-ray in this reaction is obtained.
