Abstract
There exist model calculations showing the modification of the hadronic parameters of ρ meson in the nuclear environment. From these parameters, we extract the ρ-meson-nucleus optical potential and show the medium effect due to this potential on the ρ-meson mass distribution spectra in the photonuclear reactions. The calculated results reproduced reasonably the measured e + e − invariant mass, i.e., ρ-meson mass, distribution spectra in γ, ρ 0 → e + e − reactions on nuclei.
