Spectroscopic experiment reveals multielectron cross sections in argon ion collisions with neutral atoms, highlighting the significance of capture-ionization.

Key Points

To measure single and multiple electron transition cross sections during intermediate-velocity collisions between Ar16+ ions and neutral atoms spanning perturbative to strong interaction regimes.
Used high-resolution X-ray spectroscopy to detect projectile electron transition cross sections.
Collided two-electron Ar16+ projectile ions at a fixed impact velocity of 23 a.u. with neutral noble gas targets ranging from helium to xenon.
Double excitation cross sections were well reproduced by an independent electron model across the target interaction range.
Capture-ionization cross sections were measured for the first time, demonstrating substantial contributions from this frequently neglected multielectron mechanism.
