The half-lives of 2+1 states were measured for 102,104Zr and 106,108Mo to test a new implementation of a LaBr3(Ce) array at the RIBF, RIKEN, Japan. The nuclei of interest were produced through the fission of a 345 MeV/nucleon 238U beam and selected by the BigRIPS separator. Fission fragments were implanted into the WAS3ABi active stopper, surrounding which, 18 LaBr3(Ce) detectors provided fast γ-ray detection. Timing between the LaBr3(Ce) array and plastic scintillators allowed for the measurement of half-lives of low-lying states. The preliminary results, which agree with literature values, are presented along with experimental details.
