2012Ku26: 160Pm produced and identified in 9Be(238U,F), E=1 GeV/nucleon reaction using SIS-18 synchrotron facility at GSI. Target=1.6 g/cm2 9Be placed at the entrance of projectile Fragment Separator (FRS). Particle identification was achieved by event-by-event in-flight analysis of time-of-flight, energy loss measurement, and magnetic rigidity (tof-ΔE’-Bρ). Time-of-flight 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. Isomer tagging method for known μs isomers was used to verify event-by-event identification and in-flight separation of new isotopes. Gamma rays from the known isomers were recorded in coincidence with the incoming ions using either the RISING array of Ge detectors at GSI or only two Ge detectors, a stopper foil and a scintillator for veto signal. Measured production cross section. Comparison of measured σ with predictions from ABRABLA model and EPAX-3 model
2017Wu04: 9Be(238U,F), E=345 MeV/nucleon, measured in-flight fission fragments separated and identified by BigRIPS separator and ZeroDegree Spectrometer (ZDS); measured delayed Eγ, Iγ using WAS3ABi active stopper and EURICA γ-ray spectrometer and extracted T1/2’s; deduced Gamow-Teller strength functions and r-process abundance pattern in the solar system; theoretical calculations using FRDM+QRPA, KTUY+GT2, and RHB+pn-RQRPA models. Positively identified and measured T1/2 for 94 n-rich nuclides
2020Or03: 160Pm produced at CARIBU facility (ANL) from 252Cf fission source. Ions in charge state 2+ were mass separated, collected in rf quadrupole cooler/buncher and purified in multireflection time-of-flight mass separator (δ-tof). Measured cyclotron frequencies using Canadian Penning Trap (CPT) with phase-imaging ion-cyclotron-resonance (π-ICR) technique and deduced masses and excitation energies of isomers.
Q-value: S(2n)=9931.1 22, S(2p)=23320 300 (syst), Q(β-n)=1242 6 (2021Wa16)
