Abstract
New and interesting results are presented which complement our previously published conclusions on the presence of a superoxide phase in the near-surface region of superconducting ceramic lanthanum cuprate. Although we disagree with some of the data interpretation of Zhou, Sinha, and Goodenough [this issue, Phys. Rev. B 39, 12331 (1989)] their Comment nevertheless emphasizes the difficulties in determining the species responsible for the observed superconductivity in the absence of a direct spectroscopic probe of excess oxygen in the bulk material.
