Abstract
In a recent paper [Phys. Rev. B 51, 16 487 (1995)] Zhao and Morris arg ued that the oxygen isotope substitution affects the value of the effe ctive mass of the carrier, and such effect is manifested in the isotop ic dependence of the penetration depth. The aim of this Comment is to point out serious inconsistencies in their analysis and to clarify the situation.
