Evidence For Radiative Double Electron Capture (RDEC) In F~(9+) On Carbon Collisions

摘要

Radiative double electron capture (RDEC) is a charge exchange process involving the capture of two target electrons into a bound state of the projectile with simultaneous emission of a single photon. RDEC is the time-reversed process of double photoionization if the target electrons are loosely bound. Some problems involved with electronelectron correlations can be best treated using this approach for fully-stripped ions. The current work aimed to observe x rays associated with projectile charge-changing of single and double electron capture and no charge change by F~(9+) ions and to compare with recent work for O~(8+) ions and with theory.
