Abstract
Using a 14-m2 neon hodoscope installed under 800 g/cm2 of concrete and vertically below the 32-m2 neon hodoscope, observations have been made on the strongly interacting and the muon component in air shower cores. A preliminary analysis has yielded the following results: (a) The energy spectrum of strongly interacting particles in air shower cores has been obtained in the energy range from 1 to 10 TeV, yielding an exponent of ~ −1.2 for the integral spectrum. (b) The lateral distribution of muons exhibits a distribution as steep as r−0.9 ± 0.1 down to distances of the order of 1 m from the air shower axis. However, at the present state of evaluation contamination of muon data, due to unrecognized cascades, cannot be ruled out completely.Keywords
