【摘要】 101Mo是裂变燃耗诊断的重要核素之一,它的半衰期短,准确测定101Mo核衰变数据的难度大。本工作采用强度平衡法和全程记录法测量101Mo和101Tc的γ射线发射几率Pγ。101MoPγ的强度平衡法测量结果比全程记录法的测定结果高5%,而101TcPγ的两种方法测定结果在不确定度范围内一致。有关101Mo的γ射线发射几率测量方法及其测定值有待进行进一步研究和测定。更多还原

【Abstract】 ¹⁰¹Mo is one of the key nuclides in diagnosing fission burn-up.However,it’s difficult to measure its nuclear decay data due to its short half-life.Present study（con-）（cerns） in the measurements of γ-ray emission probabilities,P_γ,of ¹⁰¹Mo and ¹⁰¹Tc using the balance of scheme method and the entire process recording.The P_γ of ¹⁰¹Mo by the entire process recording is about 5% lower than that by using the balance of scheme method.The P_γ of ¹⁰¹Tc using the two methods agree each other very well.So,it seems the γ-ray emission probabilities as well as measurement method still need study further for ¹⁰¹Mo.更多还原
