Abstract

Süperiletken lehim alaşımları SnIn (20:80, 35:65; 45:55, 65:30, 75:25) ağırlık%+Bi(%6 ağırlık)'nin K-kabuğu floresans parametreleri, X-ışını yoğunluk oranları (Ki/Kj), üretim tesir kesitleri (σKi) ve floresans verimleri (wK), Ultra-Düşük Ge dedektörü kullanılarak incelenmiştir. Numuneler, 241Am halka şeklinde radyoaktif bir kaynaktan gelen 59.5 keV γ-ışınları ile uyarılmıştır. Elde edilen sonuçlar teorik değerlerle karşılaştırılmıştır. Gözlenen veriler, alaşım etkisinin ve element bileşimi arasındaki yük transferinin teorik değerlerden sapmalara neden olduğunu göstermiştir.

Evaluation on K shell Fluorescence Parameters of Lead-Free Superconducting Alloys

Abstract

The fluorescence parameters of the K-shell such as X-ray intensity ratios (Ki/Kj,) the production cross-sections (σKi,) the fluorescence yields (wK) of the superconducting solder alloys SnIn (20:80,35:65;45:55,65:30,75:25) wt%+Bi(6)wt% were investigated by using Ultra-Low Ge detector. The samples were irradiated by 59.5 keV γ-rays from an 241Am annular radioactive source. The obtained results were compared to theoretical values. The observed data showed that alloying effect and charge transfer between the elemental composition induce the deviations with the theoretical values.
