The spectra of <sup>20</sup>Na and <sup>20</sup>F obtained by charge exchange reactions on <sup>20</sup>Ne are compared; differences are seen close to the respective break-up thresholds. The excitation energies of 16 levels in <sup>20</sup>Na have been obtained and spins assigned from DWBA calculations are compared with predictions of the shell model. In <sup>20</sup>F, a strongly excited state is seen at 6.75 MeV, but the intruder state at 3.17 MeV is very weak.
