Microscopic approach for then-deffective interaction

Abstract
A three-boson model is applied to the nucleon-deuteron (n-d) system to construct an effective energy-dependent two-body potential in configuration space. The three-nucleon observables at low energy are well reproduced with just one free parameter (related with the range of the nucleon-nucleon interaction). We show that the present results give support to a previous phenomenological n-d potential.
