EXCITATION-ENERGIES IN NA-20 ABOVE THE PROTON THRESHOLD

The level structure of Na-20 above the proton threshold has been inves tigated in the past by charge exchange reactions and by the resonant s cattering of a radioactive Ne-19 beam on a hydrogen target. A discrepa ncy was found between the two sets of experiments for the excitation e nergy of the state at approximate to 3050 keV, which led to discussion s about systematic deviations in the results of the different methods. We have reanalyaed the data of one of the (He-3,t) experiments and fi nd an agreement with the results of the scattering experiment.
