Mass of ¹³O:We adopt the 1984 Wapstra atomic mass excess of 23111 ± 10 keV. ¹³O is then bound with respect to ¹²N + p and ¹¹C + 2p by 1.516 and 2.117 MeV, respectively. See also (81AJ01).

1. 13O(β+)13N

Qm = 17.765

The half-life of ¹³O is 8.90 ± 0.20 msec. ¹³O decays to a number of states of ¹³N some of which subsequently decay to ¹²C*(0, 4.4): see Table 13.21 (in PDF or PS) (ES70). See also (81AJ01) and (KO81K; theor.).

2. 12C(p, π-)13O

Qm = -155.389

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 analog region in ¹³B.] The angular distribution of the π^- to ¹³O_g.s. has been measured at E_p = 200 MeV (HO80M), as has A_y at E_{pol. p} = 205 MeV (JA82A). See also (AU81A, GR82F, HO82C, WA82B, JA84I) and (CO81O; theor.).

3. 13C(π+, π-)13O

Qm = -19.986

At E_π⁺ = 164 MeV excited states are reported at E_x = 2.75 ± 0.04 and 4.21 MeV, as is a broad [Γ = 1.2 MeV] structure corresponding to one or more states at E_x = 6.02 ± 0.08 MeV. At E_π⁺ = 292 MeV these states are not observed. Angular distributions have been studied at E_π⁺ = 164 and 292 MeV to ¹³O_g.s. and at 164 MeV to ¹³O*(4.21) (SE84G). See also (BU80B).

4. 16O(3He, 6He)13O

Qm = -30.509
