16B (1977AJ02)(Not illustrated) This nucleus has not been observed in the 4.8 GeV proton bombardment of a uranium target: it is particle unstable (1974BO05). 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] (1974TH01, 1975JE02). See also (1973BO30), (1972TH13) and (1975BE31; theor.).
