Improved Cumulative Fission Yield Measurements with Fission Spectrum Neutrons on 235U

Nuclear Data Sheets, 2019
Abstract Two isotopically-characterized targets of high-purity (99.961±0.002%) 238U metal and a neutron dosimetry package were exposed to a pulsed neutron irradiation using the Godiva IV critical assembly at the National Criticality Experiments Research Center to measure the integral fission product yields produced in a Watt fission neutron-energy ...

Validation for Energy Dependence of Fission Product Yields of Neutron-induced 235U Fission Based on Energy Spectrum Integral Method

Yuanzineng kexue jishu
Fission product yields (FPY) have long been recognized as one of the most distinctive characteristics of the fission process, showing a strong correlation with excitation energy and the fissioning species.
