implementation of low-momentum effective interaction in spin-isospin dependent 3D approach — Shahriar Bayegan and •Mehdi Harzchi — Department of Physics, University of Tehran, P.O.Box 14395-547, Tehran, Iran

The formulation of the low-momentum effective interaction in the model space Lee-Suzuki method is implemented in a spin-isospin dependent three-dimensional approach, based on helicity representation. In this approach the low-momentum effective interaction has been formulated as a function of the magnitude of momentum vectors and the angle between them. As an application the Bonn-B potential has been used into the model space Lee-Suzuki method and it has been shown that the low-momentum effective interaction reproduces the same two-body observables obtained by the bare potential.
