¹⁹N has been produced in a number of different multinucleon transfer reactions (83AJ01, 87AJ02), and these results lead to an adopted value (93AU05) of 15.860 ± 0.016 MeV for the mass excess. ¹⁹N is then stable with respect to decay into ¹⁸N + n by 5.33 MeV. The half-life has been measured to be 0.32 ± 0.10 s (86DU07), 0.21^+0.2_-0.1 s (88MU08), 0.235 ± 0.032 s (88SA04), 0.300 ± 0.080 s (88DU1C), 0.329 ± 0.019 s (91RE02). The neutron emission probability has been measured to be P_n = 33⁺³⁴_-11% (88MU08) and P_n = 62.4 ± 2.6% (91RE02).

Excited states in ¹⁹N observed in ¹⁸O(¹⁸O, ¹⁷F)¹⁹N have been reported by (89CA25) at E_x = 1.11 ± 0.02, 1.65 ± 0.02, 2.54 ± 0.03, 3.47 ± 0.03, and 4.18 ± 0.02 MeV. See also (87AJ02, 88DU1C, 95OZ1A).

A discussion of self-consistent calculations for light neutron-rich nuclei is presented in (90LO11). Extensive shell model calculations for observables in exotic light nuclei are discussed in (93PO11). See also the shell model calculations and discussions in (92WA22).
