We have evaluated the cross section for the {pi}{sup {minus}}+{ital A}{r arrow}{pi}{sup +}+({ital A}{pi}{sup {minus}}) reaction in heavy nuclei producing deeply bound {pi}{sup {minus}} atom states still unobserved. The cross sections found, although in the measurable range, are only a small fraction of the background from the inclusive ({pi}{sup {minus}},{pi}{sup +}) reaction, which makes this experiment not very suited for the investigation of these elusive pionic states.
