 +<hidden TTP00-31 ​ Measurement of pi0 pi0 Production in the Nuclear Medium by pi- Interactions at 0.408 GeV/c > We report on an investigation of the (pi-, pi0 pi0) reaction by means 
 + of measurements of the pi0 pi0 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 2 m(pi) 
 + ​reported by the CHAOS Collaboration is not seen in our pi0 pi0 data. 
 + ​However,​ we do observe a change in the shape of the pi0 pi0 invariant 
 + mass spectrum for the different targets, indicating that the pi0 pi0 
 + ​interaction diminishes in the nuclear medium as represented by nuclei 
 + D, C, Al, and Cu, compared to hydrogen.
