摘要
Neutron radiative capture cross sections of <sup>56</sup>Fe（n,γ）<sup>57</sup>Fe 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.
