Abstract
Strong interaction level shifts and widths in atoms are analyzed by using a 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 hypernuclei are discussed.
