^{19}N (1995TI07)(See the Isobar Diagram for ^{19}N) ^{19}N has been produced in a number of different multinucleon transfer reactions (1983AJ01, 1987AJ02), and these results lead to an adopted value (1993AU05) of 15.860 ± 0.016 MeV for the mass excess. ^{19}N is then stable with respect to decay into ^{18}N + n by 5.33 MeV. The halflife has been measured to be 0.32 ± 0.10 s (1986DU07), 0.21^{+0.2}_{0.1} s (1988MU08), 0.235 ± 0.032 s (1988SA04), 0.300 ± 0.080 s (1988DUZT), 0.329 ± 0.019 s (1991RE02). The neutron emission probability has been measured to be P_{n} = 33^{+34}_{11}% (1988MU08) and P_{n} = 62.4 ± 2.6% (1991RE02). Excited states in ^{19}N observed in ^{18}O(^{18}O, ^{17}F)^{19}N have been reported by (1989CA25) 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 (1987AJ02, 1988DUZT, 1995OZ02). A discussion of selfconsistent calculations for light neutronrich nuclei is presented in (1990LO11). Extensive shell model calculations for observables in exotic light nuclei are discussed in (1993PO11). See also the shell model calculations and discussions in (1992WA22).
