This comment refers to a recent work by Raphael, Tandy, and Tobocman. The danger of incorporating cluster approximation in many-body Lippmann-Schwinger equations is emphasized. A certain type of antisymmetrization of Lippmann-Schwinger equations may lead to continuum spurious spectra. In particular it is pointed out that the cluster model equations introduced by these authors have highly suppressed (unphysical) incoming and outgoing waves. Contrary to claims made by these authors, it is stressed that Lippmann's identity is true.
