g-matrix calculations have been performed for ${}_{\mathrm{\Lambda }}{}^5{}_{}{}^{}\mathrm{He}$, ${}_{\mathrm{\Lambda }}{}^{17}{}_{}{}^{}\mathrm{O}$, and ${}_{\mathrm{\Lambda }}{}^{41}{}_{}{}^{}\mathrm{Ca}$ by solving the Λ-Σ coupled channels Bethe-Goldstone equation. The potentials employed were the Nijmegen model D and Nijmegen soft core. Calculations were performed with various choices for the Pauli-forbidden space and the energy denominator. The Nijmegen model D does a reasonable job of reproducing most experimental single-particle energies, but the calculated ground-state binding energies vary smoothly from being underbound in the ${}_{\mathrm{\Lambda }}{}^5{}_{}{}^{}\mathrm{He}$ to overbound in ${}_{\mathrm{\Lambda }}{}^{41}{}_{}{}^{}\mathrm{Ca}$. The Nijmegen soft core underbinds all single Λ states, but gives level spacings which agree with experimental values.
