摘要
对中国-日本乳胶室合作组在甘巴拉山(海拔5500m,大气深度520g/cm^2)照射的K4铁乳胶室的一部分进行了系统的扫描、测量与分析.给出了簇射事例的起始点分布,大气宇宙线高能强子的天顶角分布、垂向流强、积分能谱及其在大气和铁中的衰减长度.与其它实验组近期给出的实验数据进行了比较,几组结果大体一致.
A part of K4(1984—1985)Fe emulsion chambers exposed at Mt.Kanbala(5500m,atmospheric depth 520g/cm^2)by China-Japan Emulsion Chamber Collaboration has been analyzed with systematic scanning and measurement.The distribution of the starting point depths of the observed showers is given.The zenith angle distribution,vertical intensity,energy spectrum and attenuation length of hadrons in air and in iron are presented.Our results are compared with the recent data given by other experiments,and they are consistent with each other approximately.
