ISOMER SPECTROSCOPY AND SUB-NANOSECOND HALF-LIVE DETERMINATION IN W-178 USING THE NuBALL ARRAY

The reaction of a pulsed O-18 beam on a Dy-164 target was studied in the first experiment with the NuBall array at the IPN Orsay, France. Excited state half-lives were measured using the fast timing method with 20 LaBr3 (Ce) detectors. The timing characteristics of the fully digital acquisition system is briefly discussed. A value for the previously unknown half-life of the first excited 4(+) state in W-178 is presented
