General Comments:

2020Wu04 was compiled for the XUNDL database by B. Singh (McMaster)

1994Be24: isotope first produced by Pb(238U,F) E=750 MeV; used fragment separator (FRS) and MUSIC ionization chamber (GSI). Found 4 counts, σ=4 μb

2003Be05: isotope produced by 1-1.4 GeV protons on uranium-carbide/graphite target at PSB-ISOLDE (CERN); used 4π β detector and cylindrical 4π neutron counter. Isotope was identified by T1/2

2020Wu04: 147Xe produced by 9Be(238U,F) reaction, at E(9Be)=345 MeV/nucleon and 5pnA of intensity at RIBF-RIKEN. Fission fragments identified by determining Z vs. mass-to-charge (of ions) ratio α/Q using BigRIPS spectrometer (time-of-flight (tof), magnetic rigidity (Bρ), energy loss (ΔE) measurements). Separated ions implanted at 100 ions/s rate in WAS3ABi β counting system including DSSSDs (stack of five Double Sided Si Strip Detectors) surrounded by EURICA γ detection array (84 HPGe detectors). Measured T1/2 from implanted ions β and βγ decay curves.

Q-value: ΔQ(β-)=200, ΔS(n)=200, ΔS(p)=360, ΔQ(α)=540 (syst,2021Wa16)

Q-value: S(2n)=7050 200, S(2p)=26970 360, Q(β-n)=4840 200 (syst,2021Wa16)
