Abstract
K X-ray spectra from zirconium, niobium, molybdenum and paladium targets bo mbarded with 25 MeV/amu helium and 22.5 MeV/amu oxygen ions were measured u sing a high resolution transmission bent crystal spectrometer. Ratios of th e double to single K-shell ionization cross sections were obtained from yie lds of the K hypersatellites and diagram lines. The results are compared to the semiclassical approximation predictions within the independent-particl e model.
