Abstract

A brief review is given on development of electron-photon coincidence studies from electron impact of atoms. The theory of electron-photon correlations is outlined in detail in terms of cross sections of excited atoms and excited state charge clouds. The state of a target atom is determined by the various orientation and alignment parameters and the multipole moments of the excited atom. General considerations, such as coherence effects in impact excitation, the influence of fine and hyperfine structures in correlations are taken into account. The relationship between scattering amplitudes (including their phases) and target parameters is worked out for singlet and doublet transitions.

Özet

Bu çalışmada, atomların elektron çarpışmasıyla uyarılmasını incelemek için kullanılan elektron-foton çakışma metodunun gelişimi ayrıntılı olarak açıklanmaktadır. Elektron-foton çakışma tekniği, uyarılmış atomların tesir kesitleri ve elektron bulutları açısından ele alınarak incelenmektedir. Çarpışmadaki hedef atomun yapısı; çarpışma sırasında atoma aktarılan momentum ve uyarılmış yük bulutunun şekli ile ilgili değişik parametreler ve uyarılmış seviyenin multipol momentlerine bağlı olarak belirlenmektedir. Ayrıca atomun uyarılması sırasında ince ve aşırı ince yapı etkisi de göz önüne alınarak saçılma büyüklükleri ve hedef parametreleri arasındaki ilişki tekli ve ikili geçişler için ayrı ayrı incelenmiştir.
