Calculation of Gamma-Ray Families by Monte-Carlo Method
Abstract
Extensive Monte Carlo calculations on gamma-ray families are carried out under the appropriate model parameters currently in use in high-energy cosmic-ray phenomenology. Characteristics of gamma-ray families are systematically investigated by comparing the calculated results with experimental data obtained at mountain altitudes. The discussion involves mainly an examination of the validity of Feynman scaling in the fragmentation region of multiple meson production. It is concluded that experimental data cannot be reproduced under a scaling-law assumption when primary cosmic rays are dominated by protons. Other possibilities on primary composition and an increase in interaction cross section are also examined.
