¹⁸O(a,g)²²Ne

Wang et al. 2023

Direct measurement performed at the Jinping Underground Nuclear Astrophysics experimental facility (JUNA). The critical 470 keV resonance energy is precisely determined for the first time by direct measurement. Furthermore, the authors derived primary γ-ray branching ratios and then determine the spin-parity of the 470 keV resonance state, which resolves the resonance strength
discrepancy. Based on these new data on the resonances, this is to date the most precise reaction rate at the temperature
range of helium burning.
