2010Oh02: 84Zn nuclide identified in 9Be(238U,F) and Pb(238U,F) reactions with a 238U86+ beam energy of 345 MeV/nucleon produced by the cascade operation of the RIBF-RIKEN accelerator complex of the linear accelerator RILAC and four cyclotrons RRC, fRC, IRC and SRC. Identification of 84Zn nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments using BigRIPS fragment separator. Based on α/Q spectrum and Z versus α/Q plot, 22 counts were assigned to 84Zn isotope. Probability of misidentification of 84Zn isotope <0.001% (2010Oh02)
2014XuZZ: 84Zn produced in 9Be(238U,F),E=345 MeV/nucleon at RIBF-RIKEN facility. Measured β-decay curve, βγ-coin, T1/2 of decay of 84Zn, and %β-n or Pn.
Theoretical calculations: seven primary references for structure and four primary references for decay characteristics retrieved from the NSR database at www.nndc.bnl.gov/nsr/ are listed in ’document’ records which can be accessed via web retrieval of ENSDF database www.nndc.bnl.goc/ensdf/
Q-value: Estimated uncertainties (2021Wa16): 400 for Q(β-), 500 for S(n), 640 for S(p), 700 for Q(α).
Q-value: Q(β-n)=9360 400, S(2n)=5660 400, S(2p)=35690 890 (syst,2021Wa16). Q(β-2n)=4960 400, Q(β-3n)=1585 400 (syst, deduced by evaluator from mass excesses in 2021Wa16)
