19Na (1983AJ01)(See the Isobar Diagram for 19Na) A study of this nucleus via the 24Mg(3He, 8Li)19Na reaction at E(3He) = 76.3 MeV leads to an atomic mass excess of 12.928 ± 0.012 MeV for 19Na; it is then unstable with respect to breakup into 18Ne + p by 320 ± 13 keV. An excited state at Ex = 120 ± 10 keV is also reported (1975BE38). See also (1978AJ03, 1978GU10, 1979BE1H).
