Abstract

An efficient method for construction of an analytic S matrix from experimental data based on the use of the statistical Padé approximation is proposed. The method is applied to the energy-dependent phase-shift analysis of the elastic scattering of deuterons by alpha particles in the energy range 0.87< $E_{d}$ <5.24 MeV, and partial-wave phase shifts for l=0,1,2 are obtained. In addition, the energies and widths of the three known ${}^{6}{Li}$ resonances are obtained, together with the energy of the ${}^{6}{Li}$ bound state and the vertex constant of the virtual decay ${}^{6}\to^{2}$ H $+^{4}$ He.
