在两年的观测中,没有发现地下宇宙辐射中缓慢移动的穿透粒子的迹象。粒子速度和脉冲形状是搜索的主要标准。大气μ介子模仿慢粒子(Beta 0.1)的概率可以忽略不计。对于速度范围2 x 0.0001 beta 0.1,超重磁单极子通量的上限现在是1.86 x 10的负15次方cm(-2) sr(-1) s(-1) (90% c.l)。
No indication of slowly moving penetrating particles in cosmic radiation underground was found during two years observation. Particle velocity and pulse shape are main criteria for search. Probability of the imitation of slow particles (Beta 0.1) by atmospheric muons is negligible. Our upper limit on superheavy magnetic monopole flux is now 1.86 x 10 to the minus 15th power cm(-2) sr(-1) s(-1) (90% c.l.) for velocity range 2 x 0.0001 beta 0.1.
