Neutron-irradiated targets of natural magnesium have been analyzed by mass spectrometry in order to determine the excitation functions of neon from the energy threshold up to 20 MeV. Production cross sections of ${}_{}{}^{20,21,22}{}_{}{}^{}\mathrm{Ne}$ isotopes were measured at 5.20, 7.00, 16.20, and 19.05 MeV.
