Born-Bethe approximation to study the process of excitation atoms by electron impact

Abstract

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 .
