The lifetime of the 344-kev level of Gd/sup 152/ was measured by coincidence measurements between the beta spectrum of Eu/sup 152/ and the K conversion line of the 344-kev transition, using a double lens coincidence spectrometer. The time delay between the outcoming coincident pulses was converted to pulse height. From the calibrated shift of the centroids, using the self-comparison method, a mean lifetime of pi = (7.6 plus or minus 1.3) x 10/ sup -11/ sec was obtained. The transition probability is 20 times the single- proton value. Thus, although the level is not rotational, it has considerable collective character. (auth)
