Half-life measurement of excited states in neutron-rich nuclei

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