13O (1970AJ04)(See the Isobar Diagram for 13O) 13O has been produced in the reaction 16O(3He, 6He)13O at E(3He) = 65 MeV; the mass excess of 13O is 23.11 ± 0.07 MeV (1966CE02). 13O is then bound with respect to 12N + p by 1.54 MeV. A computation using three other members of the T = 3/2 quartet predicts M - A(13O) = 23.10 ± 0.05 (1966CE02). 13O has also been reported in the 14N(p, 2n)13O reaction initiated by 50 MeV protons: τ1/2 = 8.7 ± 0.4 msec. 13O is a delayed proton emitter decaying via 13N*(8.92, 9.52) to 12C + p. The relative intensities are 100:24; on this scale the intensities of possible transitions to 13N*(7.39; 5/2-) is < 15, log ft > 5.5 (1965MC09). On the basis of charge symmetry, and the 13B β- decay, the half-life of 13O should be 7.7 ± 0.8 msec and the β+ branching to 13N*(0, 3.51, 7.39, 8.92, 9.52) should be, respectively, (89 ± 11)%, (10 ± 2)%, (0.24 ± 0.06)%, (0.57 ± 0.12)% and < 0.2% (1969JO21).
