Abstract：
An emulsion chamber of area 5m ²and thickness 40 c.u. was installed at Mt. Kambala (5500m above the sea level), Tibet, China and exposed for one year. A γ-ray family event with ∑E_r≥800 TeV is found in the chamber. The striking feature. of the event is that most of the high energy spots are located far from the energy-weighted center of the event, while numerous low energy spots are concentrated near the energy center.
