2009St16, 2008StZY thesis: 191Ta nuclide identified in the reaction 9Be(208Pb,X), E=1 GeV/nucleon, studied at the SIS-18 accelerator facility, GSI. Target thickness=2.5 g/cm2. Fragments identified in flight by the Fragment Separator (FRS) operated in achromatic mode based on time of flight, Bρ and energy loss. Data collected on six FRS magnetic rigidity settings centered on: 206Hg, 203Ir, 202Os, 199Os, 192W, and 185Lu. Nuclides halted in a passive stopper surrounded by the RISING array in "Stopped Beam " configuration.
2014Ku02: 9Be(208Pb,X), E=1 GeV/nucleon; measured reaction products from fragmentation, production σ=(16.0 mb 32) × 10-6 for 191Ta.
