 note = {Measurements of the integrated cross sections and differntial cross sections of pion induced double pion production on nuclei Li, C, Al, Cu, In and Pb at the beam momenta of 0.5, 0.7, 0.9, 1.1, 1.3, and 1.5 GeV/c have been made. The following channels were studied: π++A→π＋＋π-+χ(1); π++A →２π++χ(2); π++A→2π-+χ(3). The data were the first systematic one. As for the differential cross sections, the shape of kinetic energy spectra were compared with each other. As for the integrated cross sections, both their mass number dependence and incident energy dependence were discussed. Furthermore the ratio of integrated cross section of channel(1) to that of channel(2) or (3) were examined. All the features observed were understood qualitatively in the following views: (a) Channel(1) and (2) are mainly contributed by single step reaction; (b) Channel(3) is mainly contributed by multi-step reaction., 1989},
