E(level): Level energies are deduced using 14O, 16Ne and p mass excesses from (2017Wa10: AME-2016). The literature reports a sizeable spread in measured values for the g.s. E(14O+2p) resonance energy, and use of any different g.s. energy would change the excitation energy scale.

| 0 | 0+ | < 80 keV % 2p = 100 | Decays 100% by 2p decay mode to 14O (2008Mu13). E(level): Decays 100% by 2p decay mode to 14O (2008Mu13). Jπ(level): From (2010Mu12,2014Br19,2015Br11). See also (2014Wa09,2015Ma09). |
| 1.77E3 | 2+ | ≤ 50 keV | Unusual correlations amongst the 14O+2p ejectiles indicate a complex interplay between direct 2p decay and sequential decay via 15F*+p (2015Br11). See also (2010Mu12). E(level): Unusual correlations amongst the 14O+2p ejectiles indicate a complex interplay between direct 2p decay and sequential decay via 15F*+p (2015Br11). See also (2010Mu12).

16Ne was first reported in 16O(π+,π-) by (1977Ho13: see 2012Th01). It is bound with respect to decay into 15F+p by 131 keV and unbound with respect to 14O+2p by 1.40 MeV. An earlier search for 2p decay radiation from 16Ne (1964Ka28) failed to find evidence of any states.
