7 × 106 events of the reaction π−N → π−π0N′ were collected at the VES experiment. Mass independent angular analysis is performed to study production mechanism of ρ-meson. t-channel ω-exchange and π-exchange are isolated. The analysis is done for 8 bins of a four momentum transfer squared to extract cross-section dependence of t′. Novel method of waves extraction is applied to deal with a significant irremovable background.
