The α0 excitation curve of Na23(p,α) reaction has been measured at proton energies in the neighbourhood of 1416 Kev. While only one resonance level was known previously in this region, we have discovered the presence of two levels, one at 1416.8 Kev (this level was known at 1415.1 Kev according to Andersen's determination of Na23(p,γ) levels, but with Ep =992.0 Kev for Al27(p, γ) reaction as standard ofenergy calibration, we have 1415.1×992.0/990.8=1416.8, and another at 1410.4 ± 1.0 Kev.The decay of this latter level is mainly through emission of a particle to the ground level of Ne20.
