Physics of Atomic Nuclei, 2002
This survey is devoted to describing the early studies of I.I. Gurevich on pion physics that were performed by the photoemulsion method and the studies of the pion-pion interaction that were made by his colleagues on the basis of the hydrogen-bubble-chamber and the magnetic-spectrometer method (as well as on the basis of the photoemulsion method).

Pion-Nucleon Scattering and Pion-Pion Interactions

Physical Review, 1962
Low energy $s$- and $p$-wave $\ensuremath{\pi}\ensuremath{-}N$ scattering is analyzed by partial wave dispersion relations. From the experimental $\ensuremath{\pi}\ensuremath{-}N$ phase shifts we derive the "discrepancies" in the physical energy region and on the crossed cut.

Pion-Pion and Pion-Kaon Scattering

Physical Review, 1960
The pseudopotential method is used to calculate that low-lying excitation energies of a Bose gas of hard spheres at T = 0 to an order beyond that previously calculated by this technique. The results are in agreement with those obthined by Beliaev using a different approach. The phonon velocity is found to be equal to the velocity of compressional waves

Pion Production and the Pion-Pion Interaction

Physical Review Letters, 1959
The cross sections for pi /sup -/ + p yields pi /sup -/ + pi /sup +/ + n at inc ident energies between 260 and 430 have been measured in a previous expeniment. A theoretical interpretation of these results is presented. An attempt is made to fit the results by using a direct pion-pion interaction.
