摘要：
Half-lives (T-1/2) of several states which decay by delayed gamma transitions were determined from time-gated triple gamma coincidence method. We determined, for the first time, the half-life of 330.6 + x state in Tc-108 and the half-life of 19/2(-) state in Te-133 based on the new level schemes. Five half-lives of Sr-95,Sr-97, Zr-99, Te-134 and Xe-137 are consistent-with the previously reported ones. These results indicate that this new method is useful for measuring the half-lives.
