    "abstract": "We perform a direct finite nucleus calculation of the partial width of a\nbound Delta isobar decaying through the non-mesonic decay mode, Delta N -\u003e NN.\nThis transition is modeled by the exchange of the long ranged pi meson and the\nshorter ranged rho meson. The contribution of this decay channel is found to be\napproximately 60 % of the decay width of the Delta particle in free space.\nConsidering the additional pionic decay mode, we conclude that the total decay\nwidth of a bound Delta resonance in nuclei is of the order of 100 MeV and,\nconsequently, no narrow Delta nuclear states exist, contrary to recent claims\nin the literature. Our results are in complete agreement with microscopic\nmany-body calculations and phenomenological approaches performed in nuclear\nmatter.",
