Abstract
In order to investigate the evolution of nuclear deformation in the region of the chart of nuclides around mass numbers A similar or equal to 110 and A similar or equal to 150, an experiment was performed at the Argonne National Laboratory where the gamma-decay radiation emitted from the fission fragments of Cf-252 was measured using 51 Gammasphere detectors coupled with 25 LaBr3 (Ce) detectors. In this work, a short description of the experimental setup is presented together with some preliminary results from the fast-timing analysis of the 4(+) state of the nucleus Zr-100. A lifetime value of tau = 50(28) ps was obtained using the Generalized Centroid Shift Method. This result agrees with the literature value of tau = 53(4) ps within one standard deviation.
