Abstract.

The analyses of (K-,π) and (π-, K+) reactions indicate that the nuclear potential of the Σ-hyperon is repulsive inside the nucleus, in agreement with the prediction of model F of the Nijmegen baryon-baryon interaction. This is consistent with the recent calculation of the strong-interaction shifts and widths of the observed levels of Σ- atoms, including the precise data on the Σ-Pb atom. In this paper, the sensitivity of this calculation to the neutron and proton density distributions is used to determine these densities in 208Pb.
