Abstract

Strong interaction level shifts and widths in Σ^- atoms are analysis by using a Σ-nucleus optical potential constructed within the relativistic mean field approach. The analysis leads to potentials with a repulsive real part in the nuclear interior. The data are sufficient to establish the size of the isovector meson-hyperon coupling. Implications to Σ-hypernuclei are discussed.
