YIELD AND ANGULAR DISTRIBUTION OF CERENKOV RADIATION FROM EXTENSIVE AIR SHOWERS
Abstract
The relative yield of Cerenkov radiation from extensive air showers and its angular distribution were measured as a function of the shower size in the range 40,000 to 2,000,000 particles. It was found that the larger showers are not as efficient in producing Cerenkov light signals as the smaller ones. The effect can be understood in light of the results on the angular distribution of Cerenkov radiation near the shower axis which was found to be more peaked fowards in larger showers. This result also leads to the conclusion that the angular distribution of electrons with energy > 21 mev near the axis of extensive air showers is dependent on the shower size. (Author)
