Аннотация:The problem of obtaining characteristics of bound nuclear states from continuum
states data is discussed. It is shown that the ambiguities due to the existence of
phase-equivalent potentials can be resolved by using the analytic properties of scattering
amplitudes. The methods of determination of asymptotic normalization coefficients and
vertex constants are considered. The asymptotic normalization coefficients for 6Li in the
α+d channel are found by analytic continuation of the two-channel effective range expansion.
The account of inelastic channels within the effective range approach is discussed.
