【摘要】 本文描述一个用大型磁云室在水平方向宇宙线穿透粒子中寻找新粒子的实验,结果表明β<0.7、m>1GeV/c²的单电荷粒子或相对论性分数电荷粒子的流强小于3×10^-8cm^-2·sr^-1·sec^-1。更多还原

【Abstract】 An experiment, using a large magnetic cloud chamber to search for new Particlesin horizontal cosmic rays is described. The result is: the flux of particles with unitcharge, β<0.7, m>1 GeV/c² or the flux of relativistic fractional charge particiles isless than 3×10^-8cm^-2sr^-1sec^-1.更多还原
