^{15}Be (1986AJ01)(Not illustrated) ^{15}Be has not been observed. The calculated mass excess is 51.18 MeV: see (1981AJ01). It is calculated to be particle unstable with respect to decay into ^{14}Be + n by 2.42 MeV. The binding energy of ^{13}Be + 2n is +0.31 MeV. See also (1981SE06, 1983ANZQ; theor.).
