dc.description.abstract	We present theoretical results for (gamma, pi(0)pi(0)) production on nucleons and nuclei in the kinematical region where the scalar isoscalar pipi amplitude is influenced by the a pole. The final-state interaction of the pions modified by the nuclear medium produces a spectacular shift of strength of the two pion invariant mass distribution induced by the moving of the sigma pole to lower masses and widths as the nuclear density increases.
