On the Potential in an Analog-State Calculation

It is shown that proper handling of the single-particle potential and the inclusion of the $1p-0h$ component in the calculations of Beres and Divadeenam give an analog state with the expected structure. The resulting ${\mathrm{½}}^{+}$ analog state in ${}_{}{}^{89}{}_{}{}^{}\mathrm{Y}$ is found to have an analog spin impurity of 0.3% and an isospin impurity of approximately 2%.
