TY - JOUR ID - TI - Born-Bethe approximation to study the process of excitation atoms by electron impact AU - Rabab M. Abdul Hassan Alaa A. Khalaf PY - 2019 VL - 37 IS - 2 SP - 153 EP - 162 JO - Basrah Journal of Science (Bas J Sci) مجلة البصرة للعلوم SN - 26648288 26648296 AB - In this paper, Born-Bethe approximation had been used to calculate the generalized oscillator strength (GOS) and cross sections (CS’s) in terms of the diploe oscillator strength (OS) for electron impact excitation of some atoms of inert gases such as He, Ne, Ar. Since the cross section depend in its formula on the GOS, it appears to us that the CS’s of He were more accurate than those of Ne & Ar atoms when we made a comparison with the experimental data, since the GOS of He was better in delicacy than Ne & Ar atoms .
