Abstract：
Delayed coincidence method was used to measure the lifetimes of the isomeric states in ¹¹⁷Xe.Two halflives of T_1/2=(59±20) ns and T_1/2=(16.5±8.0) ns have been extracted from the coincidence time spectrum between the 401keV(15/2^－→11/2^－) and the 205keV(7/2^－→5/2^＋) transitions,and are assigned to the 11/2^－ and 7/2^－ states respectively.
