Produced and identified by 1971Tr02 (1970KlZZ), 50 MeV proton induced fission of 238U, on-line mass spectrometer.
Measured β, βγ coin (1981De25,1981Ke07,1982Pa24,1986Gr11,1988GrZX); deduced Q(β).
2015YaZW: neutron rich Cs isotopes were produced at RIBF-RIKEN facility in 9Be(238U,F) reaction at E=345 MeV/nucleon. Identification of Cs isotopes was made by determining atomic Z and mass-to-charge ratio. The selectivity of ions was based on magnetic rigidity, time-of-flight and energy loss. The separated nuclei were implanted at in a stack of eight double-sided silicon-strip detector (WAS3ABi), surrounded by EURICA array of 12 cluster-type Ge detectors. with 7 crystals. Isomer of 146Cs at 47 keV was found, half-life of this state was measured.
Measurement of atomic mass: 2013Va12; CARIBU facility.
Q-value: ΔQ(α)=380 (syst, 2012Wa38)
Q-value: Q(β-n)=3880 40 (2012Wa38)
