^{13}Li (1981AJ01)(Not illustrated) ^{13}Li has not been observed. ^{13}Li is predicted to have an atomic mass excess of 61.56 MeV: it is then unstable for breakup into ^{12}Li + n and ^{11}Li + 2n by 0.6 and 4.5 MeV, respectively (1974TH01). The modified mass equation leads to a calculated atomic mass excess of 60.34 MeV: ^{13}Li would then be stable with respect to breakup into ^{12}Li + n by 0.7 MeV, assuming the a.m.u. of ^{12}Li to be 52.94 MeV, but would be unstable with respect to ^{11}Li + 2n by 3.3 MeV (1975JE02). See also (1976AJ04).
