| 0.0 | 4.6 m 3 % α ≥ 3 % ε ≤ 97 | %ε+%β+≈97 is obtained if all of the observed 230U is assumed to be formed by ε decay of 230Np following its production in 233U(p,4n). Since 230U could also be produced by 233U(p,p3n), 97% branching for ε decay was given by 1968Ha14 as an upper limit. E(level): %ε+%β+≈97 is obtained if all of the observed 230U is assumed to be formed by ε decay of 230Np following its production in 233U(p,4n). Since 230U could also be produced by 233U(p,p3n), 97% branching for ε decay was given by 1968Ha14 as an upper limit. |
Calculated half-life, Q(α): 2011Sa40
Cluster decay: 22Ne clusters (2011Sh13)
Q-value: Note: Current evaluation has used the following Q record -1698 536610 100 3263 52 6778 50 2011AuZZ
Q-value: Q(α)=6778 20 if the observed 6660α feeds the g.s. of 226Pa. Q(α) systematics suggests that 6660α feeds a low-lying level or g.s. of 226Pa.
