Chudakov etkisi nedeniyle iyonlaşma enerji kaybının bastırılması, GEANT4 simülasyon paketinden elde edilen elektron-pozitron çiftlerinin açılma açıları kullanılarak tartışılmıştır. 1-178 GeV arasındaki foton enerjileri için beklenen Borsellino ve Olsen açıları gösterilmiş ve simüle edilen açılma açıları ile karşılaştırılmıştır. Elektron-pozitron çiftinin benzetimi yapılan açılma açıları, 30 GeV'in altındaki enerjiler için Borsellino açısı ile çoğunlukla uyumludur. İyonizasyon-bastırma etkisi bilinen teorik yaklaşımlar kullanılarak yeniden üretilmiş ve ilgili simülasyon sonuçları ile karşılaştırılmıştır. Elde edilen sonuçlar, GEANT4 simülasyon paketinin teori-deney tutarlılığı sağlayan bir veri seti ile Chudakov etkisini simülasyon ortamına uyarlamak için uygun olduğunu göstermiştir.

The suppression of ionization energy loss owing to the Chudakov effect is discussed using the opening angles of the electron-positron pairs from the GEANT4 simulation package. The expected Borsellino and Olsen angles for photon energies between 1-178 GeV were presented and compared with the simulated opening angles. The simulated opening angles of the electron-positron pair are mostly compatible with the Borsellino angle for energies below 30 GeV. The ionization-suppression effect was reproduced using known theoretical approaches and compared with the corresponding simulated results. The results showed that the GEANT4 simulation package is suitable for adopting the Chudakov effect in a simulation environment, with a dataset that provides theory-experiment consistency.
