It is shown that among four models of the Nijmegen baryon-baryon interaction only model F -which leads to a repulsive potential felt by the hyperon inside the nucleus- is consistent both with the analysis of atoms and of the reactions. The Nijmegen models are used to determine the strong complex single-particle (s.p.) potential of , and to calculate the strong-interaction shifts and widths of the lowest observed levels of atoms. The results obtained with model F are in best agreement with the experimental data.
