تم، في هذا العمل، تسجيل الطيف الطاقي لكل من جسيمات ألفا الصادرة عن منبع من الراديوم-226 و منبع من الأمريسيوم-241 باستخدام كاشف نصف ناقل و غرفة تبعثر رذرفورد. تم أيضاً قياس الطاقة الضائعة الناتجة عن اجتياز جسيمات ألفا لوريقات (أهداف) من الذهب و الألمنيوم بتابعية طاقة هذه الجسيمات و بتابعية العدد الذري Z للهدف. تشير مقارنة النتائج التجريبية بالنتائج النظرية إلى وجود تطابق جيد بينهما.
In this work, we recorded the alpha spectra of radium-226 and amrecium-241 sources using a semiconductor detector and Rutherford scattering chamber. We also measured the energy loss of alpha particles in gold foil (target) and in aluminum foil as a function of alpha energy and as a function atomic number Z of the target. Comparison between experimental and theoretical results show a good agreemen.
