[ 1 ] - محاسبه سطح مقطع جزئی و کل در تقریب مرتبه دوم بورن- فادیف در برخورد پوزیترون با اتم هیدروژن در کانال تهییج

In this paper, we have implemented a three-body formalism, where the interaction potential is replaced by the transition matrix, in the excitation channel for the collision of positron and atomic hydrogen. Differential and total cross sections are calculated while the first and second order terms of the FWL (Faddeev-Watson-Lovelace) series in the transition from ground state to the first excite...
