| 抄録 | γ rays subsequent to muon in cosmic ray have been observed at near sea level between Dec.2002 and Apr.2006. The observation equipment consists of three liquid scintilation counters and is set in air conditioned observation room. The signals of cosmic ray are recorded by three strage type osciroscopes. 91 events of delayed γ ray candidate have been observed. Pulse height distrubutions have a peek at two times of single muon pulse height peek. And the delay time distributions have one peek or three peeks. These γ rays originate from muon decay and bremsstrahlung of elecrton. |
