Additional Level Data and Comments:

0.0 | 0+ | 29 s 2 % β- = 100 | E(level): νg29/2νp-21/2 configuration. |
2034.08 | 2+ | 0.31 ps 5 | XREF: E(2200). E(level): νg29/2νp-21/2 configuration. |
2511.9 | (0+) | < 15 ns | E(level): From 68Co β- decay (0.20 s). Jπ(level): Low-lying J=1 states are not expected from the available neutron fp orbitals. α strong γ to the g.s. indicates Jπ=2+ for the 2744 state. Lack of a similar transition from the 2512 state and the possible E0 transition to the g.s. supports a Jπ=0+ assignment. |

Levels: In addition to the levels given here, peaks are reported in 70Zn(14C,16O) at 2700 40, with L=0,2, at 3280 50 with L=2,4, and at 3450 50 and 4120 50. The 70Zn(14C,16O) level at 2200 30, with L=2 appears to correspond to the 2034 level but the large energy difference makes it difficult to give unique associations for any of the other peaks.
Q-value: Note: Current evaluation has used the following Q record 2103 4 7792 4 15431 7 -10919 6 2011AuZZ
Q-value: S(2n)=13600 3; S(2p)=27974 5; Q(β-n) = -4216 3 (2011AuZZ)
