Abstract
It is shown that among four models of the Nijmegen baryon-baryon interactio n, only model F is consistent both with the analysis of Sigma (-) atoms and (K-, pi) reactions. Simple estimates of the strong-interaction shifts and widths of the lowest observed levels of Sigma (-) atoms are applied for mod el F with satisfying results. It is concluded that model F is favored as a realistic representation of the SigmaN interaction.
