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