X-ray emission from highly-charged ions after electron transfer in slow collisions: the role of multiple capture processes

[摘要] We have studied 15 keV/q Ar17+impact on atomic Ar experimentally and theoretically. Our analysis shows that multiple capture processes followed by autoionization contribute strongly to the measured Lyman X-ray emission intensities in the heliumlike projectile.
