Data set first introduced in ENSDF database by F.γ. Kondev based on the XUNDL compilation of 2017Wu04 also done by F.γ. Kondev (ANL) (including Supplemental Material table of 94 measured β-decay half-lives)
2017Wu04, 2020Wu04: The 153Ba nuclide was produced at the RIBF-RIKEN facility using the 9Be(238U,F) reaction at E=345 MeV/nucleon. 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.
2017Wu04 gave the first positive identification of 153Ba nuclide and T1/2 measurement. 2020Wu04 (same group) reconfirm 153Ba production and retrieve consistent T1/2 value at higher uncertainty.
1994Be24: Identification in reaction: Pb(238U,F) at 750 MeV/nucleon. Residual products Fragment Recoil Separator (FRS), time-of-flight technique.
