The Q-value of the ⁴⁸Ca(¹⁸O, ⁵¹V)¹⁵B reaction is -21.768 ± 0.025 MeV, leading to an atomic mass excess of 28969.5 ± 25 keV for ¹⁵B (1983HO08) based on the masses of ¹⁸O, ⁴⁸Ca and ⁵¹V in (1985WA02). Wapstra adopts 28970 ± 22 keV and we shall also. ¹⁵B is then stable with respect to ¹⁴B + n by 2.765 MeV. At E(¹⁸O) = 108 MeV, dσ/dΩ = 2.0 μb/sr at 5° (1983HO08). The β^- decay of ¹⁵B has been reported: τ_1/2 = 11 ± 1 msec. Upper limits have been set on the P_0n and P_2n: 5% and 1.5%, respectively (1984DU15). See also (1981AJ01) for the earlier work, (1984HI1A, 1984MU27), (1980AL1F) and (1981SE06, 1983ANZQ; theor.).
