title: [Primary study on damage effects of low energy ions on tyrosine aqueous solution].
abstract: Low energy ions were produced in gas arc discharge, and the ions were accelerated into tyrosine (Tyr) aqueous solution. Changs in UV and infrared spectra of Tyr after this kind of ions' action were investigated. It was showed that the ions caused various damages on Tyr molecules. The ions not only destroyed the molecules, but also synthesize were new chemical groups with elements in the solution, then the new groups were inserted into the damage fragments to generate new substances. This is called "ions deposition" damage effects of low energy ions on substances.
