²⁰C has not been observed in the 4.8 GeV proton irradiation of a uranium target (1974BO05). The mass excess is predicted to be 37.17 MeV (1974TH01), 37.41 MeV (1976JA23, 1976WA18). Assuming the mass excess of ²⁰C to be 37.3 MeV, ²⁰C is then stable with respect to ¹⁹C + n and ¹⁸C + 2n by 3.2 and 4.2 MeV, respectively [see ¹⁸C and ¹⁹C]. See also (1972TH13) and (1971ST40, 1975BE31, 1976BE1G; theor.).
