General Comments:

Data set based on the XUNDL compilation of 2017Wu04 done by F.γ. Kondev (ANL) (including Supplemental Material table of 94 measured β-decay half-lives)

2017Wu04: The 153Ce nuclide was produced at the RIBF-RIKEN facility using the 9Be(238U,F) reaction at E=345 MeV/nucleon. Two experiments, optimized for the transmission of 158Nd and 170Dy ions, were carried out with average beam intensities of 7 pnA and 12 pnA, respectively. The identification of the nuclide of interest was made in the BigRIPS separator by determining the atomic number and the mass-to-charge ratio of the ion using the tof-Bρ-ΔE method. The reaction products were transported through the ZeroDegree Spectrometer and implanted into the beta-counting system WAS3ABi that was surrounded by the EURICA array comprising of 84 HPGe detectors. The typical implantation rate was about 100 ions/s. Measured: implanted ion-β--t, implanted ion-β--γ-t and implanted ions-γ-t correlations. Deduced: T1/2.

1997Be12, 1994Be24: 153Ce was observed in projectile fission of 238U at a beam energy of 750 MeV per nucleon with a fragment separator (no decay or structure data were measured)

Q-value: Estimated uncertainties (2017Wa10): ΔQ(β-)=500, ΔS(n)=280, ΔS(p)=360, ΔS(α)=480

Q-value: S(2n)=9830 200, S(2p)=24550 450, Q(β-n)=780 200, from 2017Wa10 (based on syst)
