WWW TUNL

This nucleus has not been observed in the 4.8 GeV proton bombardment of a uranium target: it is particle unstable (BO74A). Its mass excess is predicted to be 37.97 MeV: it would then be unstable with respect to decay into ¹⁵B + n by 1.1 MeV, assuming the ¹⁵B mass excess is 28.8 MeV [both mass excesses calculated using the transverse form of the mass equation] (TH74, JE75). See also (BO73BB), (TH72K) and (BE75Q; theor.).
