摘要：

The Na-22(p,gamma) Mg-23 reaction has been investigated in the energy range of E(p) = 0.20-0.63 MeV, using a Na-22 implanted target. A new resonance has been found at E(p) = 213 keV, The known resonances at E(p) = 290 and 613 keV have also been observed and have been used to determine the resonance strength omega gamma of the new resonance. A new gamma-branch for the E(x) = 7854 keV state in Mg-23, corresponding to the E(p) = 290 keV resonance, has been found, The changes in the stellar reaction rates are discussed.
