Abstract AR
تم استعمال النيوترانات الحرارية المولدة من المعجل المتواجد بجامعة الملك فهد للبترول و المعادن لأداء تحاليل عنصرية على عينات نقدية من المملكة العربية السعودية يتراوح تاريخ إصدارها ما بين 1958 و 1987م.
و العناصر التي تم تحديد نسبها في العينات النقدية هي : النحاس بنسب تصل إلى 75 % و النيكل بنسب تصل إلى 25 % و المنغنيز بنسب لا تتجاوز 0.5 %.
هذه النسب موافقة للنسب المتعارف عليها دوليا، و لقد تم إجراء هذا البحث للتأكد من جودة طريقة التحليل و صلاحية المعمل لإجراء مثل هذه التحاليل.

The accelerator-based thermal-neutron activation analysis setup at KFUPM has an adequate thermal-neutron flux that can be advantageously used for the elemental analysis of a variety of samples including archaeological ones.
The thermal neutrons are derived from the moderation of fast neutrons from the D (d, n)3He reaction which produces fast 2.5 MeV neutrons.
A maximum thermal flux of about 2.5 × 106 n / cm2-s was achieved.
For the purpose of determining the suitability of the setup for the analysis of contemporary and ancient coins, we carried out a feasibility study by irradiating a selected number of Saudi Arabian coins dating from 1958 to 1987 in the thermal-neutron flux.
The induced gamma-ray activities were then counted using a HP-GMX detector coupled to a PC-based data acquisition and analysis system.
The elements that were determined in the coins were copper (around 75 %), nickel (around 25 %), and manganese (< 0.5 %).
Calibration curves were also established for these elements.
The determined concentrations are in agreement with the data published by the Standard Catalogue of World Coins.
