title: [Changes of infrared spectra for amino acids induced by low energy ions].
abstract: Low energy ions have been generated from implanter and gas arc discharge at normal pressure, and impacted on amino acids in solid state and in aqueous solution. The induced changes of infrared spectra have been investigated. It showed that ions generated by these two means have the same or similar damage effects, such as rearrangement of damaged molecules and deposition of external ions, and the damage effects are especially remarkable and various when ions attack molecules in solution.
