TheP +19Nes- wave resonant state in20Na at stellar energies
The first excited state above the p +19Ne threshold in20Na has been identified at 2.637 MeV (± 15 keV) with Jπ=0+ or 1+ from the20Ne(3He, t)20Na reaction, suggesting this state to be the s-wave resonance in the p +19Ne scattering at stellar energies.
