Abstract
In a survey of mesons ending in the emulsion no τ- or κ-mesons have been observed so far. The variation of the negative–positive π-meson ratio with energy shows up the effect of the Coulomb barrier on π-meson production at very low energies. The variations of this ratio at mountain and balloon altitudes are discussed. Examples have been obtained of the emission of slow π-mesons in hydrogen collisions in the emulsion, and also in energetic stars with several shower particles and few evaporation particles.
