| 0+X | 0.9 s 2 % α = 100 % ε = ? % SF = ? | Spontaneous fission (SF) was observed decaying with T1/2=1.0 s +10-3. Part of this decay has been assigned to electron-capture delayed spontaneous fission (ε-SF) (2010An08). E(level): Spontaneous fission (SF) was observed decaying with T1/2=1.0 s +10-3. Part of this decay has been assigned to electron-capture delayed spontaneous fission (ε-SF) (2010An08). | |
| 0+Y | 4.4 s 8 % ε > 77 % α < 23 | Activity produced by 209Bi(40Ar,3n), E=198 MeV. Measured emitted α particles, γ rays of 252- and 279 keV (possibly E1 or E2) in coincidence with α particles; Eα=8178 keV 10 (%Iα<23) (2010An08). E(level): Activity produced by 209Bi(40Ar,3n), E=198 MeV. Measured emitted α particles, γ rays of 252- and 279 keV (possibly E1 or E2) in coincidence with α particles; Eα=8178 keV 10 (%Iα<23) (2010An08). |
