摘要
介绍了用在不同符合时间窗条件下布居和退激同质异能态的γ跃迁之间的符合强度比确定布居较弱的高自旋同质异能态寿命的方法。并用这种方法成功地确定了１９７Ｂｉ的４个同质异能态的寿命。
A method is presented to determine the half life of weakly populated high spin isomeric state from the coincident intensity ratio between the γ rays feeding and depopulating the isomer measured under different coincidence time windows Half lives for four isomeric states in 197 Bi were obtained by using this method
