Mass of ¹³O:From the Q-value of the ¹⁶O(³He, ⁶He)¹³O reaction [Q₀ = -30.508 ± 0.010 MeV] (see reaction 4) the atomic mass excess of ¹³O is determined to be 23.108 ± 0.010 MeV. ¹³O is then bound with respect to ¹²N + p and ¹¹C + 2p by 1.519 and 2.120 MeV, respectively.

1. 13O(β+)13N

Qm = 17.762

The half-life of ¹³O is 8.90 ± 0.20 msec: see (ES70) and (76AJ04). ¹³O decays to a number of states of ¹³N some of which subsequently decay to ¹²C*(0, 4.4): see Table 13.24 (in PDF or PS) (ES70). See also (RA78F) and (MA77R, RI77D, DE79C; theor.).

2. 12C(p, π-)13O

Qm = -155.386

At E_p = 613 MeV the ground state of ¹³O and an excited state at E_x = 2.82 ± 0.24 MeV are observed in addition to unresolved structures (CO78M) [see Fig. 4 for analogue region in ¹³B]. See also (HO79H).

3. 13C(π+, π-)13O

Qm = -19.983

See (GR79F).

4. 16O(3He, 6He)13O	Qm = -30.508
	Q0 = -30.506 ± 0.013 (TR71);
	Q0 = -30.513 ± 0.015 (ME70E); recalculated on basis of 9C
	mass excess of 28.912 MeV (see (79AJ01)).

The ground state of ¹³O has been populated at E(³He) = 62.6 to 68.6 MeV (ME70E, TR71).
