天体物理学的f18 (p, α) o15速率在很大程度上决定了可观测到的放射性同位素18f在新星中产生的程度。然而，由于强亚阈共振的未知性质及其可能与更高共振的干扰，这个速率一直非常不确定。新的核结构和天体物理喷射实验（JENSA）气体喷射靶首次用于确定这一重要共振的自旋，并显著降低了f18 (p, α) o15速率的不确定性。
The astrophysical F 18 (p, α) O 15 rate determines, in large part, the extent to which the observable radioisotope 18 F is produced in novae. This rate, however, has been extremely uncertain owing to the unknown properties of a strong subthreshold resonance and its possible interference with higher-lying resonances. The new Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas-jet target has been used for the first time to determine the spin of this important resonance and significantly reduce uncertainties in the F 18 (p, α) O 15 rate.
