A study of relation between Cherenkov light distribution and character of cosmic rays by Monte Carlo method[J]. Nuclear techniques, 2000, (7): 462-466.DOI:
The density distribution of Cherenkov lights produced by cosmic rays of γ
p and Fe was simulated by Monte Carlo method. The results showed that the slope of the density distribution of Cherenkov lights produced by Fe was obviously flatter than those produced by γ and p
if energy of the primaries was in the range around the " knee" of the energy spectrum. Furthermore
a special distance from the shower core was found
at which the densities of Cherenkov lights produced by the three kinds of primaries are equal. These features may be favourable for estimating the shower energy and may give some criteria to distinguish the light primaries from the heavy ones.
