2016Go26, 2016Bl05: 67Kr produced and identified at RIBF-RIKEN facility in 9Be(78Kr,X) reaction at E=345 MeV/nucleon with beam intensity of up to 250 pnA. Identification of 67Kr was made by determining atomic Z and mass-to-charge ratio α/Q, where Q=charge state of the ions. The selectivity of ions was based on magnetic rigidity, time-of-flight and energy loss using BigRIPS separator and Zero degree spectrometer ZDS. The separated nuclei were implanted in a wide range silicon-strip stopper array for ion and β particle detection WAS3ABi, consisting of three highly-segmented 1 mm thick double-sided silicon detectors, a stack of ten segmented 1 mm thick single-sided silicon strip detectors. The γ rays were detected by EURICA array of 84 HPGe detectors surrounding the WAS3ABi system. α total of 348 nuclei of 67Kr were identified at the BigRIPS spectrometer, 82 at the Zero-Degree Spectrometer (ZDS), and finally 36 implanted at the WAS3ABi detection system.
