Pion, pion-pion, and pion-nucleus interactions

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

Pions, Vancouver

International Journal of Radiation Oncology*Biology*Physics, 1982
Clinical treatments at TRIUMF started in November, 1979. Ten patients with malignant subcutaneous nodules had 14 lesions treated with pions and 37 other nodules treated with 280 kV X rays. Three different fractionation regimens were used with X ray doses spanning the expected RBE range of pions.

Pion-Pion Interaction in Electromagnetic Processes

Physical Review, 1960
The correction to the photon propagator due to the emission of a virtual pion pair is evaluated considering the effect of the strong pion-pion interaction in the J = 1, T = 1 state of the pions recently discussed by several authors. Results are given for different sets of parameters describing the pion form factor, and the pcssibility of investigating ...

Evidence Concerning Pion-Pion Interactions below the 765-Mev Pion-Pion Resonance

Physical Review, 1962
A search has been made for pion-pion resonances in the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}+p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}+{\ensuremath{\pi}}^{0}+p$ at incident pion energies of 871 Mev and 775 Mev, using a sodium-iodide luminescent chamber as a detector. The spectra of ${m}^{*}$, the total energy of the two pions
