7Be在Au中衰变率的精确测量
High Precision Measurement of Decay Rate of 7Be in Au
-
摘要: 对在通常实验室环境下注入到Au中的7Be发生电子俘获的半衰期进行测量。共测量4.8个半衰期，测得T1/2=（53.245±0.003） d。此测量结果可作为研究7Be衰变率随环境不同而发生变化时的参照值。Abstract: The half-life of the 7Be in gold sample at the normal laboratory environment is measured for 4.8 half-lives.The measured value T1/2=(53.245±0.003) d can be used as a reference in study of the variation of the decay rate of 7Be in different environment.
