E(level): From a least-squares fit to γ-ray energies where available and the rest from (t,p), unless otherwise noted. E(γ): Values from (18O,16Oγ) seem systematically higher as compared to those in β- decay, (t,pγ) and 160Gd(36S,38Sγ): 4 keV for 1296γ, 5 keV for 1538γ | ||||||||

Additional Level data and comments:
E(level) | Comments |
0 | T1/2(level): weighted average of 172 min 1 (1958Ne10), 169.6 min 7 (1971En01), and 170.0 min 8 (1972Vi11). |
1292.02 | μ=+0.26 10 (2006St21,2006Da08), B(E2)=0.0235 30 (1996Sc31) Jπ(level): L(t,p)=2 from 0+. T1/2(level): from B(E2)|^=0.0235 30 in Coulomb excitation (1996Sc31). Other: >0.31 ps from DSAM in (t,pγ). |
2805.1 | Jπ(level): 1513γ to 2+; 0 and 4 less likely from RUL; shell-model predicts 2+ (1994Fo04) in 160Gd(36S,38Sγ). T1/2(level): from DSAM in (t,pγ). |
2825.3 | Jπ(level): L(t,p)=4 from 0+. T1/2(level): from DSAM in (t,pγ). |

3658 | XREF: E(3690)K(3674)L(3674). E(level): Jπ(level): L(t,p)=5,6; γ to 4+; shell-model predicts 6+ (1994Fo04) in 160Gd(36S,38Sγ). |

1292.02 | 1292.0 | E(γ): weighted average of 1292.3 4 from 38P β- decay (0.64 s) and 1291.9 2 from (t,pγ). Others: 1296.2 4 from (18O,16Oγ), 1292 4 from (48Ca,Xγ), 1286 19 from Coulomb excitation. |
2805.1 | 1513 | E(γ): from (t,pγ). Other: 1515 6 from (48Ca,Xγ) |
2825.3 | 1533.2 | E(γ): from (t,pγ). Other: 1538.2 5 from (18O,16Oγ), 1534 5 from (48Ca,Xγ) |
3658 | 833 | E(γ): from (48Ca,Xγ). Other: 849 from (36S,38Sγ) |
3725.3 | 900 | E(γ): from (18O,16Oγ) with value adjusted by 3 keV lower than the original value=903 1 since all values in that dataset are systematically lower than values in other studies. |
4990.2 | 3698.0 | E(γ): from 38P β- decay |
