Calcium DoubleK-Shell Ionization Produced from 24.0- to 48.0-MeV Oxygen Bombardment

Abstract
We have measured relative x-ray-production cross sections for Ca Kα satellite and hypersatellite transitions produced from 24.0- to 48.0-MeV oxygen bombardment of thick targets. All cross-section ratios as functions of projectile energy for initial defect configurations KkLl, where k=1, 2 and l=0, 1, 2, 3, 4, are in qualitative agreement with configuration-space binary-encounter-approximation predictions.
