A study of the ⁴⁸Ca(¹⁸O, ¹⁹N)⁴⁷Sc reaction leads to a mass excess of 15.872 ± 0.020 MeV for ¹⁹N (HO83C). This and earlier results [see (83AJ01)] lead to an adopted (WA85C) value of 15.873 ± 0.019 MeV. ¹⁹N is then stable with respect to decay into ¹⁸N + n by 5.32 MeV. The half-life of ¹⁹N is reported to be 0.32 ± 0.10 sec (DU86G), 0.21^+0.2_-0.1 sec (MU87D). See also (KL84A) and reaction 8 in ¹⁹O. P_n ~ 33% (MU87D; prelim.). In addition to the ground-state transition (NA82) report the population of states of ¹⁹N at E_x = 1.12 ± 0.04 and 1.59 ± 0.04 MeV. See also (HI84, HU86E, PI86C), (DE83U, WI83H, AN86U, GU86H) and (CU82A, AN83D, FR83G; theor.).
