^{19}N (1983AJ01)(See the Isobar Diagram for ^{19}N) Studies of the ^{18}O(^{18}O, ^{17}F)^{19}N and ^{208}Pb(^{18}O, ^{207}Bi)^{19}N reactions at E(^{18}O) = 91 and 93 MeV, respectively, lead to values of the atomic mass excess of ^{19}N of 15.856 ± 0.050 (1982NA08) and 15.96 ± 0.15 MeV (1979BA31). The adopted value is 15.866 ± 0.048 MeV. ^{19}N is then stable with respect to decay into ^{18}N + n by 5.45 MeV. Differential cross sections for the two reactions in which ^{19}N has been observed are ~ 500 nb/sr (6°) (1982NA08) and ~ 120 nb/sr (85°) (1979BA31). In addition to the groundstate transition, (1982NA08) report the population of states at E_{x} = 1.12 ± 0.04 and 1.59 ± 0.04 MeV. See also (1980AL1F, 1980NA12) and (1978AJ03).
