【Abstract】 A new method is established for measuring nuclear fission number.In this method,the gamma ray total counts of 3—5MeV energy region is utilized.In this paper,the feasibility of this method is verified by irradiation experiment of enriched uranium sample.The results show that this method can be used to measure number of nuclear fission.Compared with the result of general method,the uncertainty in the measurement of this method is less than 16%.It is of worth-while further research.更多还原
