Study of Secondary Particles Produced by 200 and 500 GeV Protons in Emulsion Chambers

摘要

The objectives are: (1) Comparison between the beam energy and the primary energy as determined by properties of secondary particles, in order to check the method currently used in cosmic ray experiments; (2) The distribution of energy given to gamma-rays and the distribution of elasticity of collisions; and (3) Search for short-lived particles as found by the author in an emulsion chamber exposed to cosmic rays.
