[ 1 ] - محاسبه سطح مقطع کل تهییج در برخورد یون برهنه+Aq با اتم هیدروژن در گذار از حالت پایه به حالت‌های 2s و 3s در تقریب بورن- فادیف
In this work, total excitation cross section of atomic hydrogen in the collision of bare ion was calculated employing a three body Faddeev formalism. In the present calculation, initially the first order electronic amplitude was calculated using the interaction potential which led to inelastic form factor. Secondly, the first order nuclear amplitude was calculated and added to the first order ...
[ 2 ] - محاسبه سطح مقطع دیفرانسیلی و کل تهییج تک الکترونی هلیوم در برخورد با پروتون در انرژی‌های میانی و بالا به روش فرمول‌بندی سه جسمی
A three-body model is devised to study differential and total cross sections for the excitation of helium atom under impact of energetic protons. The actual process is a four body one but in the present model the process is simplified into a three-body one. In this model, an electron of helium atom is assumed to be inactive and only one electron of the atom is active. Therefore, the active ele...
