Abstract

Cross sections for production of target-atom carbon K x rays in thin evaporated carbon films are determined from spectra obtained using a double-focusing soft-x-ray spectrometer with calibrated transmission. A maximum value of 2.3 × 10-19 cm2 is found for 18-MeV oxygen ions. A maximum ionization cross section of 4.8 × 10-17 cm2 is estimated from the data. Cross sections for x rays on both sides of the carbon K edge are determined. Nitrogen ions produce more L-shell ionization at low energies than carbon or oxygen ions, both of which create very few KL2 satellite x rays below about 9 MeV.
