Abstract：
A gamma-ray family event with the showers distributed in the form of two concentric rings has been found in the Mt.Kanbala Emulsion Chamber experiment.The radii of the two rings are 4mm and 10mm respectively.This event exhibits some features clearly deviated from those of ordinaly big families.In this paper,some charateristic features of the rings are analysed and short discussion is made.
