Ion time-of-flight spectroscopy: krypton charge-state spectra as a function of photon excitation energy near the K edge
In this experiment, we have recorded the charge state distribution resulting from atomic rearrangement following the creation of the inner shell vacancies in krypton atoms. Intense, highly collimated, monochromatic and tunable x-ray radiation available at the CHESS synchrotron radiation facility at Cornell was used to photoionize krypton atoms in a gas jet target, and a time-of-flight spectrometer was used to record the ions in different charge states formed after photoionization. Charge state spectra were recorded at below, at the peak in the K edge and above the edge. Below the edge, charge states +4 to +7 were observed with appreciable intensity, while at, and above the edge, the charge states ranged from +4 to +10.
