Production of Meson Showers

  title={Production of Meson Showers},
  author={W. Heisenberg},
IT was noticed long ago that the special type of interaction between the nucleons and the particles responsible for nuclear forces leads to the possibility of production of many such mesons in one single act1,2. This result has later been disputed, especially by Heitler and his co-workers3, with the argument that the same interaction could possibly produce a strong damping effect as well, which might prevent any multiple production of particles. Jánossy4 then put forward the view that some… Expand
The nuclear interactions of cosmic rays
This report deals with the types of nuclear interaction, the properties of nuclear-interacting particles, and the correlation of nuclear events in the atmosphere and in condensed matter. TheExpand
Evidence for the multiple production of mesons in a single nucleon-nucleon collision
SummaryEvidence has been obtained for the multiple production of mesons in a single nucleon-nucleon collision in a photographic emulsion exposed to the cosmic radiation at an altitude of 95 000 ft.Expand
On nuclear explosions produced by primary protons in emulsions exposed in the high atmosphere
SummaryNuclear explosions produced by cosmic radiation have been studied in Ilford G5, 400 μ emulsions, which were exposed at about 60 g/cm2 from the top of the atmosphere for about two hours. TheExpand
Hadronic Interactions and Cascades
After a brief introduction we discuss the hadronic cross sections for interactions that are of relevance for air shower and ultrahigh energy physics research, such as cross sections and theExpand
Further Observations of Cosmic-Ray Events in Nuclear Emulsions Exposed Below Ground
Ilford Nuclear research plates were manufactured in a laboratory at an equivalent depth of 60 m. of water below ground. After having been stored at various depths, the plates were processed belowExpand
Transverse momentum of secondary particles produced in high-energy nuclear interactions
