K- Shell Ionization of Chlorine and Argon due to Impact of Alpha Particles

Abstract

In the present work, K-shell ionization cross-sections of Chlorine andArgon due to alpha impact have been calculated through the BinaryEncounter Approximation model. The effects of Coulomb deflection ofthe projectile under the influence of target nucleusand increase in bindingenergy of the target electron because of presence of the projectile insideK- shell of the target have been incorporated.The cross-sections have beenaveraged over Hartree-Fock momentum distribution for the targetelectron. The calculated cross-sections have been found in satisfactoryagreement with the available experimental values and other calculatedresults
