Abstract: The lifetime of the ((11/2)-) state at 267keV in 125Cs was measured. A Ge detector with the transistor reset preamplifier(TRP Ge) was used to measure delayed <Gamma>-rays under an intense prompt background. The B(M2) value deduced from the lifetime was found to be consistent with the Weisskopf estimate.
