Abstract AR
تم حساب إزاحات الطور و المقاطع العرضية التفاضلية (DCS's) و المقاطع العرضية الكلية (TCS's) و المقاطع العرضية للزخم المنتقل (MTCS's) للبوزترونات عند الطاقات الواطئة و المتوسطة لذرات الغازات الخاملة (النيون, الاركون, الكربتون و الزينون). اعتمدت هذه النظرية على ربط الجهد المستقر (الاستاتيكي) مع جهد الاستقطاب الثنائي و الرباعي عند المسافات الطويلة و مع الجهد الترابطي للباحث Ashok Jain.
عند المسافات القصيرة وجدنا أن هناك توافق جيد لنتائجنا مع النتائج العملية و النظرية المتوفرة لباحثين آخرين.
Abstract EN
We have calculated the phase shifts, differential cross sections (DCS’s), total cross sections (TCS’s) and momentum transfer cross sections (MTCS’s) for the positrons scattered elastically from Ne, Ar, Kr and Xe atoms.
The theoretical method is based on combining the static potential with the polarisation potential (containing both dipole and quadrupole polarisabilities) at long distances and with the correlation potential of Ashok Jain at short distances.
We found a good general agreement with other experimental and theoretical values of many investigators.
