利用4疴-γ符合装置和低能光子谱仪精确测量了161Tb衰变γ射线的发射几率。对于25.7 keV、48.9 keV和74.6 keV的低能γ射线
测定结果分别为0.2327 0.0053、0.1700 0.0031和0.1001 0.0019。表明本测量结果的不确定度明显减小。
Emission Probabilities for the low-energy γ-rays following the decay of 161Tb were measured precisely by using a 4疴-γ coincidence apparatus and low-energy photon spectrometer. Determined results are 0.2327 0.0053
0.1700 0.0031 and 0.1001 0.0019 for the 25.7
48.9 and 74.6 keV γ-rays
respectively. The uncertainty of the present measurement has been considerably decreased as compared with previous data.
