Single and double electron capture associated with target K‐shell ionization for F7 + ,8 + ,9++Ar

Ratios for target Ar K‐shell ionization associated with single and double electron capture, as well as the ratios corresponding to total capture and the projectile K x rays, were determined for 1.8‐ to 2.2‐MeV/u F7 + ,8 + ,9+ projectiles. This work was performed at Western Michigan University with t...

Description
Summary:Ratios for target Ar K‐shell ionization associated with single and double electron capture, as well as the ratios corresponding to total capture and the projectile K x rays, were determined for 1.8‐ to 2.2‐MeV/u F7 + ,8 + ,9+ projectiles. This work was performed at Western Michigan University with the tandem Van de Graaff accelerator. Coincidences between emitted K‐shell X‐rays (both target and projectile) and the corresponding charge‐changed particles were observed. The F9+ Ar K X‐ray coincidence ratios for double to single capture are found to well exceed unity over the limited energy range of the measurements. Possible explanations for this anomalous behavior are discussed.
