General Comments:

2009St16, 2008StZY (thesis): 194W 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.

2009Al30, 2011St21, 2014Ku02: production yields and cross section measured.

  00+ % β- = 100
While no decay mode has been experimentally observed, evaluators assign %β-=100 by inference, as β- is the only decay mode energetically possible.
E(level): While no decay mode has been experimentally observed, evaluators assign %β-=100 by inference, as β- is the only decay mode energetically possible.
