Abstract A methcd of measuring half lives is proposed to determine isomeric states decaying slower than 10/sup -14/ seconds. The principle is explained by a hypothetical case in which two K-ccnversion electrons are emitted in cascade. The time between these two events can be determined by fising the start time of the first electron from its phase position in a high frequency voltage supplied between two condenser plates. The second electron emitted in coindence with the first one obtains a deflection which is a function of the phase difference with respect to the first one. Test arrangements and variations of the method are discussed. (J.R.D.)
