英文摘要	X-ray spectra of K-shell hollow krypton atoms produced in single collisions with 52-197-MeV/u Xe54+ ions are measured in a heavy-ion storage ring equipped with an internal gas-jet target. Energy shifts of the K alpha(s)(1,2) , K alpha(h,s)(1,2) , and K beta(s)(1,3) transitions are obtained. Thus the average number of the spectator L vacancies presented during the x-ray emission is deduced. From the relative intensities of the K alpha(s)(1,2) and K alpha(h,s)(1,2) transitions, the ratio of K-shell hollow krypton to singly K-shell ionized atoms is determined to be 14%-24%. In the considered collisions, the K vacancies are mainly created by the direct ionization which cannot be calculated within the perturbation descriptions. The experimental results are compared with a relativistic coupled-channel calculation performed within the independent particle approximation.
