Observation of the shadowing of cosmic rays by the Moon using a deep underground detector

Journal Article (Journal Article)

Using data collected by the MACRO experiment during the years 1989–1996, we show evidence for the shadow of the Moon in the underground cosmic ray flux with a significance of 3.6σ. This detection of the shadowing effect is the first by an underground detector. A maximum-likelihood analysis is used to determine that the angular resolution of the apparatus is [Formula Presented] These results demonstrate MACRO’s capabilities as a muon telescope by confirming its absolute pointing ability and quantifying its angular resolution. © 1998 The American Physical Society.
