Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0 | (1/2-) | 22 s 4 % β- = 100 | Configuration=ν(p1/2-1). The assignment is tentative. |
| 367.0 | (5/2-) | E(level): Tentative assignment proposed in 2013Mo20. It is also possible that the 12 s activity is associated with the ground state β- decay of 203Ir, as the isomer is not observed in 2011St21. Jπ(level): Based on shell model predictions and similarity with the 205Hg and 207Pb (n=125) isotones. | |
| 1367 | (13/2+) | 12 s 5 % IT = ? % β- = ? | Configuration=ν(i13/2-1). The assignment is tentative. E(level): Tentative assignment proposed in 2013Mo20. It is also possible that the 12 s activity is associated with the ground state β- decay of 203Ir, as the isomer is not observed in 2011St21. Jπ(level): Based on shell model predictions and similarity with the 205Hg and 207Pb (n=125) isotones. |
| 1367+X | (27/2-) | Configuration=ν(i13/2-1)π[h11/2-1,d3/2-17-]. The assignment is tentative. E(level): From 2011St21. Jπ(level): From 2011St21. | |
| 2471.0+X | (33/2+) | 641 ns 55 | Configuration=ν(i13/2-1)π[(h11/2-2)10+]. The assignment is tentative. E(level): From 2011St21. Jπ(level): From 2011St21. |
| E(level) | E(gamma) | Comments |
| 367.0 | 367 | E(γ): From 2013Mo20. In coincidence with the Pt Kα2 x rays and shows a 12 s lifetime |
| 1367 | 1000.0 | E(γ): Weighted average from the observed 925 keV 13 and 986 keV 3 K- and L-ce lines in coincidence with 367γ in 2013Mo20 (Be-(K)=78.395 keV and Be-(L)=13.880 keV) |
| 2471.0+X | 1104.0 | E(γ): From 2011St21 |
