Abstract

The fluorescence yield was determined for the Ar

L

shell by measuring absolute cross sections for Ar

L

x-ray and Auger-electron emission for 30- to 600-keV

H^{+}

,

H_{2}^{+}

, and

{He}^{+}

ions on Ar. When the Auger-electron spectrum was analyzed, the fluorescence yield for

{He}^{+}

was found to be an order of magnitude larger than existing theoretical estimates.
