Resonant-state solution of the Faddeev-Merkuriev integral equations for three-body systems with Coulomb potentials

Abstract

A novel method for calculating resonances in three-body Coulombic systems is proposed. The Faddeev-Merkuriev integral equations are solved by applying the Coulomb-Sturmian separable expansion method. The $e^- e^+ e^-$ S-state resonances up to $n=5$ threshold are calculated.
