Azot Molekülünün İkili Diferansiyel Tesir Kesiti Ölçümleri

Abstract

In this study, electron impact ionization cross sections of nitrogen molecule are presented. In electron collision experiments, electron beam with specific energy interacts with target gas and the outgoing particles are detected with respect to their scattering angle and energy. The outgoing particles are quantum particles that are interacted with each other. Scattering phenomena can be understood only if the interaction potential and particle’s wavefunctions are correctly determined. In the thesis, electron impact scattering and ionization process for N2at 250 eV incident electron energy is investigated. Calibration studies are completed before the DDCS measurements are done. In this sense, elastic and inelastic scattering of electron-N2 collision is searched for different kinematics.Measurements are completed in Electron Collision Laboratory (e-COL) located in AfyonKocatepe University.

Bu çalışmada, elektron etkisi ile Azot molekülünün ikili diferansiyel tesir kesiti ölçümleri yapılmıştır. Elektron çarpışma deneylerinde, belirli enerjideki elektron demeti hedef gaz molekülleri ile çarpıştırılmakta ve çarpışma sonucu ortaya çıkan parçacıklar açı ve enerjilerine göre dedekte edilmektedir. Çarpışma sonucu saçılanelektronlar, birbirleriyle etkileşen kuantum parçacıklarıdır. Saçılma olayının anlaşılması, etkileşme potansiyelinin ve parçacıkların dalga fonksiyonlarının doğru ifade edilmesiyle mümkündür. Bu tez çalışmasında Azot molekülünün 250 eV enerjili elektron demeti ile saçılma ve iyonlaşma tesir kesitleri ölçülmüştür. İkinci aşama olarak Azot molekülünde farklı enerji ve açı değerlerinde DDCS ölçümleri yapılmıştır. Ölçümler, Afyon Kocatepe Üniversitesi Elektron Çarpışma Laboratuvarında (e-COL) bulunan elektron spektrometresi kullanılarak alınmıştır.
