This nucleus has not been observed in the 4.8 GeV proton bombardment of a uranium target: it is particle unstable. Its mass excess is predicted to be 37.97 MeV: it would then be unstable with respect to decay into ¹⁵B + n by 0.93 MeV: see (1982AJ01, 1985WA02). The ground state is predicted to have J^π = 0^- and the first three excited states are predicted to lie at 0.95, 1.10, and 1.55 MeV [J^π = 2^-, 3^-, 4^-] in a (0 + 1)ℏω space shell model calculation (1985PO10). See also (1983ANZQ; theor.).
