Finite-range effects in hadronic atoms. (II). Kaonic and antiprotonic atoms

Finite-range effects leading to a nonlocal optical-model description of strong-interaction level shifts and widths were studied for kaonic and antiprotonic atoms by using a coordinate-space code which had been introduced and successfully applied to fitting pionic atom data. Some difficulties, which are encountered when strong-interaction bound states appear near zero energy, are analyzed and discussed. By fitting to selected kaonic-atom and antiprotonic-atom data, the present analysis finds substantially larger ranges than for pionic atoms. These values are discussed within the context of several hadron-nucleon interaction models and nuclear multiple-scattering approaches.
