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
The emission probability of 14 7Nd 5 3 1 keVγ rays was accurately measured with a 4πβ γ coincidence device and a HPGe γ spectrometer, and the measured result was (1 3 1 1 ± 0 1 7)%. Compared with the previously reported data, the accuracy of the measurement results improved significantly
