摘要：

以N+、H+、Ar+三种离子分别辐照固态甲酸钠样品，经电子顺磁共振（EPR），红外光谱（IR）的检测. 结果发现，三种低能离子辐照后的甲酸钠样品中产生了COO-自由基和亚甲基（－CH_2）．同时，结合茚三酮反应，证明了辐照后的甲酸钠样品中还含有新的基团──氨基（NH_2），并给出了氨基的产生量与注入离子的剂量和能量的相关曲线．

Abstract:

Solid HCOONa sample was implanted by ions such as N+、H+、Ar+、with the same energy. The induced damage was detected by EPR and infrared (IR) spectra. It showed that the-CH2- group and COO- radical ion could be produced in implanted HCOONa sample with N+、H+、Ar、ions. By using the analysis of the highly sensitive ninhydrin reaction. It was proved that NH2 group could be produced by N+ ion beam.
