Girişim etkilerinin dahil edildiği koherent x-ışını saçılma verileri plastikler için elde edilmiştir.  Moleküler girişimin etkisini belirlemek için, moleküler form faktörler hesaplanmıştır.  Moleküler form faktörlerin teorik sonuçları literatürdeki deneysel değerler ile karşılaştırılmıştır.  Moleküler form faktörler düşük momentum transfer değerleri için önemli bir biçimde değişmektedir.  Bunun sonucu olarak, çok düşük foton enerjileri için, koherent saçılma tesir kesitlerinde önemli bir değişim gözlenmektedir. Girişim etkileri, moleküler form faktör ve coherent saçılma tesir kesiti farklılıklarının ana sebebidir.  Bu çalışmada elde edilen sonuçlar, foton transfer problemlerini modelleyenler tarafından kullanılması için kayda değer veri temin edecektir.

Coherent X-ray scattering data for plastics

Öz

Coherent x-ray scattering data including molecular interference effects are obtained for plastics.  To determine the effect of molecular interference, the molecular form factors are calculated.  The theoretical results of molecular form factors are compared with experimental values in literature.  The molecular form factors varies importantly for low momentum transfer values.  As a result of this, for very low photon energies, a significant change in the coherent scattering cross sections is observed.  The interference effects are the main cause of form factor and coherent scattering coefficient differences.  The results obtained in this study will provide remarkable data for use by others to model photon transport problems.
