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