Abstract
A three-particle variational calculation of the cross sections and phases of elastic Λ-d scattering in the doublet and quartet states with zero orbital angular momentum is carried out in the energy range from 0 to 20 MeV (laboratory system of coordinates). The calculation is carried out with semirealistic N-N Afnan-Tang potentials and Λ-N potent: Λ—N, which describe Λ-p scattering correctly, as well as the binding energy of the hyperfragments 5Λ He, 13Λ C (within the scope of the Λ + core model), and 3Λ H (considered as a three-body system).
