20C (1978AJ03)


(Not illustrated)

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.).
