Singh (McMaster); Jan 9, 2013 92BR c {+238}U beam at E=345 MeV/nucleon provided by the RIBF accelerator 92BR2c complex at RIKEN facility. Fission fragments were separated and 92BR3c analyzed by BigRIPS separator, transported to focal plane of 92BR4c ZeroDegree spectrometer and finally implanted in an aluminum stopper. 92BR5c Particle identification was achieved by |DE-tof-B|r method. 92BR6c Delayed gamma rays from microsecond isomers were detected by three 92BR7c clover-type HPGe detectors. Measured E|g, I|g, |g|g-coin, isomer 92BR8c half-life. Deduced levels.

Identification of nuclei was made on the 92BR5c basis of magnetic rigidity, time-of-flight and energy loss of the 92BR6c fragments (|DE-B|r-tof method) using BigRIPS fragment separator 92BR7c and ZeroDegree Spectrometer (ZDS) at RIBF-RIKEN facility. 92BR8c Fragments implanted into the Advanced Implantation Detector Array 92BR9c (AIDA) for beta and ion detection surrounded by the BRIKEN 92BRAc neutron counter. Deduced half life and delayed neutron emission 92BRBc probability. 92BR L 0 334 MS 14 92BR2 L %B-N=49.9 18 (2025To04) 92BR cL T$quoted uncertainty includes both statistical and systematic 92BR2cL uncertainties (2025To04) 92BR cL %B-N$half-life was fixed to literature value in order to 92BR2cL improved the accuracy of the %|b-n fit.
