摘要
对1972年8月在海拔3200m高山上利用大型云室组研究甚高能核作用的数据,进行了日计数率随时间变化的分析研究,发现在8月4日和8月7日两个大的太阳质子耀斑期间,事例计数率高出邻近期间日平均计数率的标准偏差三倍。其相应的初级宇宙线能量为10^(13)eV左右.
We have analyzed and studied the time variation of the daily counting rates of the very high-energy events observed by a large cloud-chamber system during August 1972 at a mountain altitude of 3200 meters above sea-level. An obvious increase of counting rates occurred during the 4th and 7th, August, 1972 solar cosmic ray flares is found. These daily counting rates are higher than 3σ of the daily counting rate averaged from 10th to 26th, August. The average energy of the events corresponds to a primary cosmic-ray energy of 10^(13)eV.
