| 0.0 | 1.0 s 2 % α > 70 % SF < 30 | Calculated: T1/2(α)=2 s, T1/2(ε+β+)=60 s, T1/2(SF)=20 s, deduced from Q values (1995KoZL); T1/2(α)≈0.1 s (1990Ha26); T1/2(SF)≈400 s, T1/2(α)≈30 s (1988Lo03). | |
| 0.0+Y | 0.12 s % IT = ? % α = ? | Reported as a member of α chain from 271110 (1997Ho03,1997Ho13). 1997Au04 cites T1/2=0.36 s 13 from an earlier report by same authors. E(level): Reported as a member of α chain from 271110 (1997Ho03,1997Ho13). 1997Au04 cites T1/2=0.36 s 13 from an earlier report by same authors. |
