An equation relating the shift and width of atomic levels to the strong scattering length, which was derived previously )T. L. Trueman, Nucl. Phys. 26, 57 (1961); A. E. Kudryavtsev and V. S. Popov, Pis'ma Zh. Eksp. Teor. Fiz. 29, 311 (1979) (JETP Lett. 29, 280 (1979)); V. S. Popov, A. E. Kudryavtsev, and V. D. Mir, Zh. Eksp. Teor. Fiz. 77, 1727 (1979) (Sov. Phys. JETP 50, 865 (1979))), is generalized to the case of complex momenta k and arbitrary values of the angular momentum l and of zeta = -Z/sub 1/Z/sub 2/. The shift and width of the s levels of the ..sigma../sup -/p atom are calculated. The relationship between the position and width of the resonances in the case of Coulomb repulsion is studied.
