The momenta of secondary charaged particles from ir~ -meson interactions with nuclei at 50 GeV were measured by an emulsion method in a strong magnetic field. It is shown that the average transverse momenta and the fractions of the energy carried away by particles with opposite charges depend little on the target-nucleus dimensions. The data do not agree with the concept that the primary pion is completely passive after collision at 50 GeV.
