Ground-state $\alpha$-spectroscopic factors for ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$, ${}_{}{}^{24,26}{}_{}{}^{}\mathrm{Mg}$, and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ have been determined via the ($d$,${}_{}{}^6{}_{}{}^{}\mathrm{Li}$) reaction at $E_d=80\mathrm{}$ MeV. The results are compared with theoretical shell-model predictions. Relative spectroscopic factors for the excited $2^{+}$ and $4^{+}$ states in ${}_{}{}^{36}{}_{}{}^{}\mathrm{Ar}$ are also presented.
