1. 18N(β-)18O

Qm = 14.06

The half-life of ¹⁸N is 0.63 ± 0.03 sec (CH64G): E_β(max) = 9.4 ± 0.4 MeV. The decay is to ¹⁸O*(4.46), which subsequently decays via ¹⁸O*(3.63, 1.98) [see reaction 21 in ¹⁸O]. The allowed nature [log ft = 4.88] of the decay to the 1^- state at 4.46 MeV leads to J^π = 0^-, 1^- or 2^- for the ¹⁸N ground state (CH64G).

2. 18O(π-, γ)18N

Qm = 125.51

Preliminary results show the excitation of the ¹⁸N ground state and of another group with E_x ~ 7.5 MeV (TR76D).

3. 18O(n, p)18N

Qm = -13.27

See (CH64G).

4. 18O(t, 3He)18N	Qm = -14.04
	Q0 = -14.038 ± 0.030 MeV (ST69B).
