Electron capture and deprotonation processes observed in collisions between Xe8+and multiply protonated cytochrome-C
2014
Physical Review A. Atomic, Molecular, and Optical Physics
Electron-transfer processes in interaction between highly charged ions and multiply protonated proteins have been studied. Collisions between Xe 8+ at 96 keV and protonated cytochrome-C at selected charge state (q from 15+ to 19+) result in mass spectra composed mainly of intact molecular ions. From the spectra, single and double electron capture processes by Xe 8+ from the protonated molecular ions were identified and the relative cross sections were measured. An unexpected process, the
