Separated resonances in simultaneous capture and excitation ofS15+inH2observed byK-x-ray–K-x-ray coincidences

We have measured cross sections for the correlated emission of two K x rays following the collision of hydrogenlike sulfur ions with ${\mathrm{H}}_2$ in the energy range between 70 and 160 MeV. The observation of the two correlated x rays is interpreted as a resonant capture of a target electron accompanied by simultaneous excitation of the projectile in the collision (RTE). By our distinguishing between Kα and Kβ lines, contributions from KLL and KLn (n≥M) resonances could be determined independently.
