147Nd 531 keVγ射线发射几率的精确测量
Precise Measurement of the Emission Probability for the 531 keV γ-ray of 147Nd
【摘要】 用 4πβ γ符合装置和HPGeγ谱仪精确测量了14 7Nd 5 3 1keVγ射线的发射几率 ,测量结果为(1 3 1 1± 0 1 7) %。与以往报道的数据相比较 ,本测量结果的准确度明显改善
【Abstract】 Emission probability for the 531 keV γ ray of 147 Nd is measured by using a 4πβ γ coincidence apparatus and HPGe γ ray spectrometer. The result is (13.11±0.17)% . The present result is considerably improved in comparison with previously reported values.
