我们报告的第一次测量的上行μ介子的流量产生的大气中微子在岩石下面的宏观相互作用。在所有最低点角上积分的观测事件数与预期事件数之比为0.73 ±.09统计值±.06系统值±.12理论值。上行μ子通量作为最低点角的函数，并与蒙特卡罗的预期。在90%的置信水平，数据是一致的，没有中微子振荡或一些可能的振荡假说与神冈包含事件分析建议的参数。
We report on the first measurement of the flux of upgoing muons resulting from interactions of atmospheric neutrinos in the rock below MACRO. The ratio of the observed to the expected number of events integrated over all nadir angles is 0.73 ± .09stat.± .06sys.± .12theor.. The flux of upgoing muons as a function of nadir angle is presented and compared to Monte Carlo expectations. At the 90% confidence level, the data are consistent with no neutrino oscillations or some possible oscillation hypothese with the parameters suggested by the Kamiokande contained-event analysis.
