We present the results of the analysis of diffractive reaction π-Be → π-π0π0 measured with upgraded VES detector with the statistics of about 16 · 106 events. The mass-independent partial-wave analysis is performed using set of 70 partial waves corresponding to natural-parity exchange mechanism and restricting the rank of spin-density matrix Nr = 1. The data is divided into 40 MeV m(3n) bins and in 10 intervals of momentum transfer squared t. The sub-density-matrix of mass independent PWA is subject to further mass dependent fits using Breit-Wigner resonant terms and coherent non-resonant backgrounds. [ABSTRACT FROM AUTHOR]
