Pv. Magnus et al., THE HOT CNO CYCLE N-13(P,GAMMA) RESONANCE ENERGY AND THE NE-18 MASS, Physical review. C. Nuclear physics, 49(4), 1994, pp. 1755-1758
The masses of Ne-18, and of the O-14 first excited state that dominate
s the astrophysical N-13(p, gamma) reaction rate, were measured using
the O-16(He-3,n) and C-12(He-3,n) reactions. We found mass excesses of
5316.8 +/- 1.5 keV for the Ne-18 ground state and 13163.4 +/- 2.0 keV
for the first excited state of O-14. The O-14 MasS Corresponds to an
N-13(p, gamma) resonance energy of 528.8 +/- 2.0 keV. This is consiste
nt with the result from a recent N-13+p study, but disagrees with the
previously accepted value. Implications for the thermonuclear N-13(p,
gamma) rate are discussed.
