Abstract

The Rayleigh scattering cross-sections were determined in the region of 22≤ Z ≤82 at 1260 using an energy dispersive X-ray fluorescence spectrometer at 59.5 keV energy and a Si(Li) detector. This paper presents and discusses the results of this study. The predictions of several form factor theories were compared with experimental Rayleigh scattering differential cross-sections

Rayleigh Şaçılma Üzerine Deneysel Bir Çalışma

Abstract

Bu çalışmada, Rayleigh saçılma diferansiyel tesir kesitleri enerji ayrımlı X-ışını flöresans spektrometreyle 22≤ Z ≤82 bölgesinde 1260 lik saçılma açısında ölçüldü. Deneyde 59.5 keV enerjili fotonlar ve bir Si(Li) dedektörü kullanıldı. Sonuçlar bu makalede sunuldu ve tartışıldı. Deneysel Rayleigh saçılma diferansiyel tesir kesitleri farklı form faktör teorilerinin sonuçlarıyla karşılaştırıldı.
