Abstract

L_β/L_a
X-ray intensity ratios of antimony (Sb) were investigated at different
azimuthal (-30° ≤ φ ≤+30°, at intervals of 10°) and polar scattering angles
(85°≤ θ ≤135° at intervals of 10°). In the purpose of exciting to Sb and
detecting the X-rays emitted from Sb, ²⁴¹ Am point source and Si(Li)
detector have been used, respectively. The data was analysed by means of Origin
9 Software and it was determined that L_β/L_a
change by polar scattering angle at a fixed azimuthal scattering angle and by azimuthal scattering angle at a
fixed polar scattering angle.

Keywords

Intensity ratios, azimuthal scattering angle, polar scattering angle

Farklı Azimuthal ve Saçılma Açılarında Antimonun Lβ/L Şiddet Oranları

Abstract

Sb’
nin L_β / L_a X-ışını şiddet oranları farklı azimuthal ve
saçılma açılarında ölçüldü. Sb’ yi uyarmak amacıyla ve Sb’den gelen X-ışınların
saymak amacıyla ²⁴¹ Am nokta kaynak ve Si(Li) dedektör sırasıyla
kullanıldı. Datalar Origin 9 programı aracılığıyla analiz edildi ve L_β /
L_a şiddet oranlarının farklı azimuthal açı ve
saçılma açısı değerleriyle değiştiği belirlendi

Keywords

Şiddet oranları, azimuthal saçılma açısı, , polar saçılma açısı.
