The intrashell quartet states proposed earlier on the basis of intrinsic multiconfiguration Hartree-Fock calculations are reexamined for ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ in angular momentum projection formalism and supports in favor of the existence of such states are obtained. Quartet correlation in excited states of ${}_{}{}^{22}{}_{}{}^{}\mathrm{Ne}$ has also been investigated.
