Analytic continuation of scattering data as a method of obtaining characteristics of bound states

Abstract

The method of the analytic continuation of the effective range function is applied to obtain the asymptotic normalization coefficients for 6Li nucleus in the α+d channel. Several sets of scattering phases obtained from the phase-shift analyses as well as from Faddeev calculations are used as an input. Since the α+d system possesses the low-lying inelastic threshold due to the dissociation of a deuteron, the approach used is generalized to include inelastic channels. The sensitivity of the obtained values of asymptotic normalization coefficients to the elastic channels coupling and to account of the inelastic channel is investigated.
