英文摘要	110 keV Fe+ ion beams supplied by 200 kV ion injector were implanted into film samples of L(+) -cysteine hydrochloride monohydrate. The dose was 2.5 x 10(16) ions (.) cm(-2). After the implantation, the film samples were scraped down and simply mixed together in the solid state. The samples before and after ion implantation were tested on FTIR, HPLC and ESI-FTMS spectroscope respectively. The two results of FTIR spectroscopic tests of the ion-implanted samples were different, which showed that radiolysis might have taken place at different sites of the film. But there is certain similarity between the two results in that they both showed the damages of the amino, carboxyl and sulfhydryl groups, and so on, of the original molecules and the formation of new nitro groups. The formation of many new molecules with various molecular weights was determined by HPLC and FTMS analysis and radiolysis of amino acid derivatives induced by the irradiation of 110 keV Fe+ ion beams was confirmed.
