2017Wu04: 155La nuclide produced at RIBF-RIKEN facility using 9Be(238U,F) reaction at E=345 MeV/nucleon. Two experiments, optimized for transmission of 158Nd and 170Dy ions, were carried out with average beam intensities of 7 pnA and 12 pnA, respectively. Identification of nuclide of interest was made in BigRIPS separator by determining the atomic number and the mass-to-charge ratio using the tof-Bρ-ΔE method. Reaction products transported through ZeroDegree Spectrometer and implanted into beta-counting system WAS3ABi surrounded by EURICA array comprising of 84 HPGe detectors. Typical implantation rate |~100 ions/s. Measured: implanted ion-β--t, implanted ion-β--γ-t and implanted ions-γ-t correlations. Deduced: T1/2.
