    "abstract": "The recent and older level shifts and widths in pbar atoms are analyzed. The\nresults are fitted by an antiproton-nucleus optical potential with two basic\ncomplex strength parameters. These parameters are related to average S and P\nwave scattering parameters in the subthreshold energy region. A fair\nconsistency of the X-ray data for all Z values, stopping pbar data and the\nNbar-N scattering data has been achieved. The determination of neutron density\nprofiles at the nuclear surface is undertaken, and the determination of the\nneutron R_{rms} radii is attempted. Uncertainties due to the input data and the\nprocedure are discussed.",
