Directional Distribution of the Hard and Soft Component of Cosmic Radiation
Abstract
With a two-fold coincidence apparatus we have determined the intensity distribution of cosmic radiation in the north-south and east-west planes. The measurements were made in all four directions with zenith angles (δ) varied by 5° steps from the vertical to the horizontal. Every position was measured once with no absorber and a second time with 36cm. lead between the counters. From the results it is possible to determine independently the directional distribution of the hard and of the soft component:
