Abstract The role of the parameter λ in pion interferometry, thecorrelation strength, is investigated. The relations between the extracted values for λ and the radii are emphasized and illustrated by a compilation of published data. It is shown that radii from interferometry measurements can often not be interpreted independently from λ. The validity of quantitative radius estimates based on the freeze-out picture is discussed. From pion interferometry data at target rapidity in 200A GeV16O+Au collisions an effective rescattering cross section for soft pions of σ≈11 mb is extracted.
