    "abstract": "The method recently proposed by Skala and Cizek for calculating perturbation\nenergies in a strict sense is ambiguous because it is expressed as a ratio of\ntwo quantities which are separately divergent. Even though this ratio comes out\nfinite and gives the correct perturbation energies, the calculational process\nmust be regularized to be justified. We examine one possible method of\nregularization and show that the proposed method gives traditional quantum\nmechanics results.",
