The level structure of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Na}$ above the proton threshold has been investigated in the past by charge exchange reactions and by the resonant scattering of a radioactive ${}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$ beam on a hydrogen target. A discrepancy was found between the two sets of experiments for the excitation energy of the state at ≊3050 keV, which led to discussions about systematic deviations in the results of the different methods. We have reanalyzed the data of one of the ${(}^3$He,t) experiments and find an agreement with the results of the scattering experiment.
