Abstract
We discuss medium modification of the meson originating from its coupling to in medium quasipions and delta-hole states. This medium effect leads to a marked structure of the meson strength function in the 500 MeV invariant mass region. We suggest that this effect may provide an explanation of the structure observed by the DLS Collaboration in the Ca+Ca/C+C ratio at 1 GeV/nucleon.
