摘要
Abstract
The principle and technique of determination of 235U/238U isotope abundance ratio by fission yield ratio were discussed. Samples were irradiated by 14. 8 MeV neutrons for short time, then y rays spectra were measured with HPGe spectrometry system. From characteristic y rays of separate fission products, the weighted average fission yields were got. Then correlative curves of 235U/Z38U isotope abundance ratio versus fission yield ratio for several product pairs were got.关键词
