New process observed in collisions between highly charged protonated protein and Xe~(8+), Xe~(5+), He~(2+) ions

摘要

Electron multicapture processes have been studied in collisions between cytochrome C protein and highly charged Xe and He projectile at keV kinetic energy range. In competition with single and double electron capture, a new and unexpected channel attributed to deprotonation process of the protein has been observed.
