The measurement of prompt fission neutron spectrum for~(238)U were carried by nuclear emulsion method by using a~(238)U metal sample in thick of 20 mm.2.5 MeV neutron was produeed by600 kV Cockroft-Walton accelerator in CIAE,and nuclear emulsion was utilized to record the proton-recoil movement track.The length,depth and angle of the track were measured through microscope.The incident neutron energy was calcu-
The measurement of prompt fission neutron spectrum for ~ (238) U was carried by nuclear emulsion method by using a ~ (238) U metal sample in thick of 20 mm.2.5 MeV neutron was produed by600 kV Cockroft-Walton accelerator in CIAE, and nuclear emulsion was utilized to record the proton-recoil movement track. The length, depth and angle of the track were measured through the microscope. The incident neutron energy was calcu-
