Abstract
We calculated the mass and width of the resonance inside nuclei within a nucleon- model by including the self-energy of the in the propagator. We found that in the nuclear medium the width of the is increased by one order of magnitude while its mass changes only by a few MeV. This broadening of the width of the resonance embedded in nuclei is consistent with the experimental observations so that the can be understood as a resonance. Thus, given the freedom between either isospin 0 or isospin 2 for the , our results give weigth to the isospin-2 assignment.
