【摘要】 用中、日合作设置在甘巴拉山(海拔5500米,大气深度520g/cm~2)上的部分K6和K7厚铅乳胶室,研究了观测能量为10—50TeV的大气宇宙线中的高能γ线与强子。给出了它们的垂向流强、积分能谱、天顶角分布及其在大气中的衰减长度。将所得结果与过去的同类结果进行了比较。更多还原

【Abstract】 Using a part of China-Japan Pb emulsion chambers (K6 K7, thick 30 c. u.) exposed at Mt. kanbala (5500 m, atmospheric depth 520 g/cm~2), the high energy gamins rays and hadrons are studied. The vertical intensities, energy spectra, zenith angle distributions and attenuation length of gamma rays and hadrons in air are presented. The results are compared with previous data. It is shown that the vertical intensity of gamma rays given by the previous work is lower than the present result and other characteristics are consistent with each other.更多还原
