| 0 | (1-) | 24 ms +12-6 % ε = ? % εp = ? % p = ? | As shown in α/Q particle identification plot in Fig. 1 of 2019Si33, a larger number of events were assigned to 76Y as compared to only two in the earlier work from RIBF-RIKEN (2017Su26). E(level): As shown in α/Q particle identification plot in Fig. 1 of 2019Si33, a larger number of events were assigned to 76Y as compared to only two in the earlier work from RIBF-RIKEN (2017Su26). |
2002Fa13, 2001Ki13, 2007WeZX: 76Y produced and identified in fragmentation of 112Sn beam at 1 GeV/nucleon on Be target at GSI facility, fragment separator. α total of two events were assigned to 76Y. This work suggested the stability of 76Y against proton emission.
2017Su26: 76Y nuclide identified in 9Be(124Xe,X), E(124Xe)=345 MeV/nucleon beam produced by the cascade operation of the RIBF accelerator complex of the linear accelerators RILAC and RILAC-II and the four cyclotrons, RRC, fRC, IRC, and SRC. Identification of 76Y nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss (tof-Bρ-ΔE method) of the fragments using BigRIPS fragment separator, atomic number Z of fragment by tof and ΔE, and α/Q (atomic mass/charge state) of fragment by Bρ and tof. Time-of-flight was measured using thin plastic scintillators, ΔE by MUSIC ionization chambers, and Bρ by particle trajectory reconstructions. Measured α/Q versus Z distributions
2019Si33: 76Y nuclei were produced at RIBF-RIKEN facility using the same experimental arrangement as in 2017Su26, except that the β-counting system was wide-range active silicon-strip stopper array for β and ion detection (WAS3ABi). Measured half-life of the decay of 76Y from (implanted ions)β-correlated decay curve.
Theoretical calculations: six primary references for structure and one for decay characteristics retrieved from the NSR database (www.nndc.bnl.gov/nsr/) are listed in this dataset under ’document’ records.
Q-value: Estimated uncertainties (2021Wa16): 420 for S(n), 370 for S(p), 580 for Q(α)
Q-value: Q(ε)=16000 300, Q(εp)=11680 300, S(2p)=910 300 (syst,2021Wa16). S(2n)=31950 (2019Mo01,theory)
