Abstract: | M-shell ionization cross sections for atoms due to the impact of proton and α-particles have been calculated in the binary
encounter approximation. The effects of Coulomb deflection of the incident projectile and increase in binding of the target
electron have been investigated. Roothan-Hartree-Fock velocity distribution for the target electrons has been used in the
present work. The calculated cross-sections have been compared with experimental results and other theoretical calculations
wherever available. The present calculations give a good account of experimental observations. |
