The reaction 22Na(p,γ)23Mg has been investigated in the energy range Ep = 0.17-1.29 MeV using a22Na implanted target, a D2O threshold detector, and NaI(Tl) and Ge detectors. Resonances in this reaction have been observed for the first time at Ep = 290, 457, 503, 613, 740 and 796 keV. The strengths of these resonances, and upper limits on the strengths for expected resonances in the energy range covered, are given. The stellar reaction rates deduced from the present work are about one order of magnitude lower than previous theoretical estimates; they are however significantly higher than the upper limits from one previous measurement. Some astrophysical consequences are discussed.
