2012Ku26: 171Tb produced and identified in 9Be(238U,F), with E=1 GeV/nucleon followed by separation using the Fragment Separator (FRS). Particle identification using event-by-event in-flight analysis of time-of-flight, energy loss and magnetic rigidity (tof-ΔE’-Bρ) measurements. Time-of-flight was measured using two plastic scintillation detectors, energy loss or deposit by ionization chambers (MUSIC), and magnetic rigidity by four time-projection chambers (TPC), which also provided energy deposit information. Measured production cross section.
2017Wu04: 171Tb produced using the 9Be(238U,F) reaction at E=345 MeV/nucleon and identification made in the BigRIPS separator by measuring the atomic number and the mass-to-charge ratio of the ion using the tof-Bρ-ΔE method. Reaction products were transported through the ZeroDegree Spectrometer and implanted into the beta-counting system WAS3ABi which was surrounded by the EURICA array consisting of 84 HPGe detectors. Measured implanted ion-β-(t), implanted ion-β--γ(t) and implanted ions-γ(t); deduced T1/2
