Abstract
The differences of space distributions and time profiles between the gamma- ray and proton induced shower particles are studied using Monte Carlo simul ation data. The multifractal analysis is performed with the G-moment method for the distribution fluctuation of secondary particles near the core of s howers induced by gamma-rays and protons. From the spectrum functions of ga mma and proton events, it is seen that this method can be adopted as a basi s for the gamma/proton separation. It is shown that the separation of gamma and proton can be achieved with a good efficiency in the energy region of 1-10TeV.
