Jπ(level): As assigned by 2009Po02 based on comparison with apparently similar level structure in 200Pt. For levels above the 16Ns isomer at 1680.8+x, the assignments are from 2008StZY

T1/2(level): From (particle) γ(t) (2009Po02,2008StZY). Note that the half-lives of the two isomers are nearly the same within uncertainties

  2224.8+X(9-)   E(level): 447-527-544 cascade placed above the 1681+x level from 2008StZY based on the statement that all three γ-rays are in coincidence with each other and all the γ-rays in 198Os shown in the level scheme in Fig. 2 of 2009Po02.
  2751.7+X   E(level): 447-527-544 cascade placed above the 1681+x level from 2008StZY based on the statement that all three γ-rays are in coincidence with each other and all the γ-rays in 198Os shown in the level scheme in Fig. 2 of 2009Po02.
