Book excerpt: The photoproduction of vector mesons on various nuclei has been studied using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Laboratory. All three vector mesons [rho], [omega] and phi are observed via their decay to e+e-. The possible in-medium effects on the properties of the [rho] meson are of particular interest. The [rho] spectral function is extracted from the data on carbon, iron and titanium, and compared to the spectrum from liquid deuterium, which is relatively free of nuclear effects. We observe no effects on the mass of the [rho] meson, some widening in titanium and iron is observed consistent with the collisional broadening.
