Infinite-rank separable expansion for the three-body T matrix at energies in the continuous spectrum region
Abstract
A method for expanding a three-particle T matrix at energies above the two-particle threshold as an infinite series of separable terms, based on the Schmidt theorem, is presented. The Yamaguchi-type separable potential is assumed for the two-nucleon interaction. The application of this expansion to the calculation of a four-body resonance is studied by giving a numerical example. The convergence of the Schmidt expansion is comparable to that of the Hilbert-Schmidt expansion at energies below the two-particle threshold.
