2009St16, 2008StZY thesis: 200Ir nuclide identified in the reaction 9Be(208Pb,X) with a beam energy of 1 GeV/nucleon produced by the SIS-18 accelerator at GSI facility. 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.
Experimental identification with a similar setup also reported in 2008St20.
2011Ji02: Calculated energy levels, spin and parity, B(E2) values, quadrupole and magnetic moments.
Q-value: Note: Current evaluation has used the following Q record
Q-value: Estimated uncertainties in 2011AuZZ: 200 for Q(β-) and S(n), 450 for S(p), 540 for Q(α)
Q-value: S(2n)=11930 280 (syst,2011AuZZ), S(2p)=18940 (1997Mo25,calculated)
