Excitation energies of the states in ${}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$ are measured via the reaction ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}({}_{}{}^3{}_{}{}^{}\mathrm{He},\alpha ){}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$ up to an excitation of ∼10.6 MeV. Angular distributions for several states are measured and analyzed by use of the conventional distorted-wave Born approximation. Relative spectroscopic factors are extracted and compared with the predictions of the spectroscopic-factor sum rule. The analysis fails to confirm an assignment of $j=\frac{3}{2}$ for the excited states at 6.01 and 6.74 MeV.
