²⁰N is particle stable. Its atomic mass excess is 21.64 ± 0.26 MeV (1986VI09), 22.20 ± 0.36 MeV (1986GI10), 21.62 ± 0.14 MeV (1987GI1E). We adopt 21.62 ± 0.14 MeV. ²⁰N is then stable with respect to ¹⁹N + n by 2.32 MeV (see ¹⁹N). The half-life of ²⁰N is 100⁺³⁰_-20 msec, P_n ≈ 61% (1987MU1J; prelim.). See also (1984KL06; theor.). See also (1985PIZZ, 1986PI09), (1983WI1A, 1984HI1A, 1986AN07, 1986GU1D) and (1983ANZQ; theor.).
