Inner-Shell Vacancy Production And Multiple Ionization Effects In 0.1-1.75 Mev/U Mn, Fe, Co, Ni, Cu Plus Au, Bi Collisions

Vacancy production in 0.1-1.75 MeV/u Mn, Fe, Co, Ni, Cu + Au, Bi collisions has been studied by measuring integral inner-shell ionization cross-sections and mean outer-shell ionization probabilities at the Tandem accelerator of NIPNE. Bucharest. X-ray spectra induced by ion beams of Mn, Fe, Co, Ni and Cu impinging on thin solid-foil targets of An and Bi have been measured. Total ionization cross-sections for the K-shell of the projectile and L-3-subshell of the target, as well as vacancy sharing probabilities, corrected for the effect of multiple ionization, are reported. The experimental results are discussed in terms of two model calculations. (C) 2003 Published by Elsevier Science B.V.
