A Superhigh Energy Gamma-Ray Family Event in the Form of Two Concentric Rings
- Received Date: 1987-12-24
Abstract: A superhigh energy gamma-ray family event with the showers distributed in the form of two concentric rings has been found in the ML Kanbala emulsion chamber experiment. The radii of the two rings are 4 mm and 10 mm respectively. This event exhibits some features clearly deviated from those of ordinary big family events. In this paper, some characteristic features of the rings are analyzed and a short discussion is made.
