摘要
Air showers recorded by the Haverah Park array during the years 1974-1987 have been re-analysed. For the original estimate of the energy spectrum, a relationship between the ground parameter rho(600) and the primary energy, as determined by Hillas in the 1970s, was used. Here we describe the energy spectrum obtained using the QGSJET98 interaction model in the CORSIKA Monte Carlo code, together with GEANT to simulate the detailed detector response to ground particles. A new energy spectrum in the range 3 x 10(17) -4 x 10(18) eV is presented. (C) 2002 Elsevier Science B.V. All rights reserved.
