[ 1 ] - Angular deviation of secondary charge particles in 1014-1016 eV extensive air showers: Constrains on application of hodoscopes
Deviation angles of secondary electrons and muons in simulated extensive air showers were studied. The angles have wide distribution, whose width depends on energy cuts imposed on shower particles. In this work, variation of deviation angles with the energy of secondary particles, shower energy, primary direction, and core distance was investigated. The results put limitations on application ...
[ 2 ] - سطح مقطع طولی در بهمنهای گسترده هوایی؛ نتایج ضمنی برای مطالعه ترکیب جرمی پرتوهای کیهانی
Nµ/Ne, muon to electron population ratio in extensive air showers at high altitudes has been shown to be a suitable estimator of primary cosmic rays mass composition. This study is based on simulated extensive air showers. The Nµ/Ne ratio has been obtained in 100 depths from the top of the atmosphere to the sea level for different primary particle masses and energies. An empirical relation bet...
