【Abstract】 Fast neutrons produced in 44GeV 12C+Cu interactions have been measured and analysed with nuclear emulsion. The neutron spectra were obtained by measuring the recoil protons in emulsion and the track parameters of a particles from interactions of 12C(n, n’)3 α in emulsion.The experimental neutron spectrum was compared with those by Monte-Carlo calculations.更多还原
