19N (1978AJ03)
(See the Isobar Diagram for 19N)
A study of the 18O(18O, 17F)19N reaction
with E(18O) = 91 MeV leads to a mass excess for 19N
of 15.81 ± 0.09 MeV: at θ=10°, dσ/dΩcm=100 nb/sr (1977DE14). 19N is then
stable with respect to breakup into 18N + n by 5.5 MeV. Another report
of the mass excess of 19N gives 15.96 ± 0.15 MeV (1977BA3V; abstract). A
previous report by (1974GU19) of the formation of 19N in
10Be(11B, 2p) and of its subsequent β-decay is
incorrect: see (1976FI03). For mass calculations see (1974TH01, 1975JE02,
1976JA23, 1976WA18, 1977WA08). See also (1972AJ02), (1972TH13,
1972WA07, 1973TO16, 1977AR06, 1977BH1B) and (1973WI15, 1975BE31;
theor.).
