Local realizations of contact interactions in two- and three-body problems
A. T. Kruppa, K. Varga, J. Revai
Abstract
Mathematically rigorous theory of the two-body contact interaction in three dimension is reviewed. Local potential realizations of this proper contact interaction are given in terms of Poschl-Teller, exponential and square-well potentials. Three body calculation is carried out for the halo nucleus 11Li using adequately represented contact interaction.
