dc.description.abstract We propose an experimental procedure to find out the medium modifications of the phi meson. The reaction is inclusive phi photoproduction in nuclei, looking for K+K- pairs from the phi decay with total momentum smaller than 100-150 MeV/c, which are made possible at energies of present laboratories from center of mass phi backward production and the help of Fermi motion. We have conducted a many body calculation of the mass distribution of the phi adapted to the experimental set up of a recent JLAB experiment where the backwards phi photoproduction has been measured. Using recent results for the in medium properties of the phi we find that the width of the invariant mass distribution fur photoproduction on medium to heavy nuclei is larger than the free rp width by a factor of two or more.
