Sažetak
We report on an investigation of the (pi^, pi^0 pi^0) reaction by means of measurements of the pi^0 pi^0 invariant mass distributions from pi^ interactions on H, D, C, Al, and Cu targets at p_pi^ = 0.408 GeV/c. The sharp, strong peak in the pi^+ pi^ invariant mass near 2m_pi reported by the CHAOS Collaboration is not seen in our pi^0 pi^0 data. However, we do observe a change in the shape of the pi^0 pi^0 invariant mass spectrum for the different targets, indicating that the pi^0 pi^0 interaction diminishes in the nuclear medium as represented by nuclei D, C, Al, and Cu, compared to hydrogen.
