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
Additional Level Data and Comments:
E(level) | Jπ(level) | T1/2(level) | Comments |
0.0 | 0+ | % β- = 100 | Only β- decay mode is possible. E(level): Only β- decay mode is possible. |
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. | ||
