| Abstract: | In preparation of homogeneous Kr and Rb sources,the Kr activity was determined by the decay relationship between 88Kr and 88Rb using an HPGe detector.The peak efficiencies of 88Kr and 88Rbγ-rays were calibrated.The results show that the absolute probabilities of 196.3,834.8,1529.8,2195.8 and 2392.1 keVγ-rays of 88Kr were 25.1（5）%,12.9（2）%,10.7（2）%,13.3（2）%and 34.9（5）%,respectively. |
