Abstract：
The characteristics of high energy γ-rays are studued using emulsion chamber installed at Mt. Ganbala, Tibet, 5500 m high above the sea level, at atmospheric depth of 520g/cm ². The vertical flux, integral energy spectrum, zenith-angle distribution and the attenuation length in the atmosphere for the high energy γ-rays are obtained. The comparsion of the results with those of the similar works shows satisfactory agreement. Several γ-ray families are selected and analyzed and the energy spectrum, fractional energy spectrum and the mean values of the transverse momentum of γ-rays in the families are obtained and discussed.
