The sample of solid sodium carboxylic and three pyrimidiyls were implanted y different ion (suchas N^+,H^+,Ar^+)of the same energy. The induced damages were deteted by EPR and infrared (IR), which showed that the CH2 group and [COO}^.^- radical ion were produced in the sodium formate sample implanted with N^+, H^+, Ar^+ ions.By using highly sensitive ninhydrin reaction, it was proved that the NH2 group was produced in the three pyrimidinyls implanted with Ar^+ ion beam. These results show that no matter what kinds of ions are used, new products including CH2 and [COO]^.^- groups can be produced in the implanted sodium formate sample. They may form from the rearrangement reactions of the target atoms. Above results are to examine the mass and energy deposition effects of low energy ion implantation. It was found that the new CN group and the NH2 group could be produced in the implanted sodium carboxylic by N^+ ion beam. It well known that the sodium formate itself has no N atom. Therefore. the produced NH2 group and CN group must result from the mass deposition effect of the implanted N^+ ion.Above results are to examine the mass and energy deposition effects of low energy o implantation.
