Abstract

K-shell x-ray emission following low-energy charge exchange collisions (≤11 eV/amu) has been measured for ten bare and hydrogenic ions up to U⁹¹⁺. The data resolve capture into angular momentum states with ℓ=1 and provide a stringent test of theory. The assumption of Stark mixing of angular momentum states is inappropriate at such energies. Results from detailed calculations give a better description of the data, but significant discrepancies are noted. The measurements show that the hardness ratio of charge-exchange induced K-shell x-ray emission represents a diagnostic of the dynamics of ion-atom interactions in situations where the energy is below 1 keV/amu, e.g., in solar wind collisions. © 2000 The American Physical Society.
