Abstract (2. Language): 
The detailed understanding of the interactions with electrons of complex molecules has an important role for the development of theoretical modellings in the atomic and molecular physics' research. Experimental studies devoted to the understanding of dynamic structures of molecules especially are used to test these theoretical modellings. In this study, experimental binding energy spectrum data of the CH4 molecule obtained by electron-electron coincidence technique using electron spectrometer in the laboratory of collision with electrons (e-COL) will be presented.

Abstract (Original Language): 
Karmaşık moleküllerin elektronlarla etkileşimlerinin ayrıntılı bir biçimde anlaşılmasının atom ve molekül fiziği araştırmalarında, kuramsal modellemelerin gelişmesinde önemli bir yeri vardır. Özellikle moleküllerin dinamik yapılarının anlaşılmasına yönelik deneysel çalışmalar, bu kuramsal modellemelerin test edilmesinde kullanılmaktadır. Bu çalışmada elektronlarla çarpışma laboratuvarında (e-COL) bulunan elektron spektrometresiyle, elektron-elektron çakışma tekniği kullanılarak alınan deneysel CH4 molekülünün bağlanma enerji spektrumu verileri sunulacaktır.
