论文摘要
通过对透射布局的核弹性后坐力检测分析，已经确定了硫化硫化物和白云母的稀薄自支撑样品中的氢浓度。分析过程仅基于停止功率和后坐力横截面的数据库进行材料分析，而无需使用任何已知H含量的参考样本。对于多苯基硫化物样品，确定的值为$（2.87 \ pm 0.26）\ times 10^{22} \，{\ rm h}/$ cm $^{3} $与计算值非常吻合，与$ 3.01 \ times 10^{22}} {22}} \，{$ cm rm h} $ cm c^3.01 \ times 10^{22}} $ CM对于麝香木样品，在样品的整个厚度上，源自结合的水和吸收水的H浓度均匀。确定的浓度$（9.43 \ pm 0.75）\ Times 10^{21} $ H $/$ CM $^{3} $的Muscovite $非常同意，价值9.36 \ times 10^{21}} $/$ h $/$ h $/$ cm $ $ $^{3} $从其他定量分析中获得的典型典型的典型应用程序。目前的结果证明了通过传输ERDA准确确定材料和矿物质中H含量的能力。
Hydrogen concentrations in thin self-supporting samples of polyphenylene sulfide and muscovite have been determined by nuclear-elastic recoil detection analysis of transmission layout. The analysis procedure is based only on the database of stopping power and recoil cross section for material analysis, without using any reference sample of known H content. For the polyphenylene sulfide sample, the determined value of $(2.87\pm 0.26)\times 10^{22}\,{\rm H}/$cm$^{3}$ is in good agreement with the calculated value of $3.01 \times 10^{22}\,{\rm H}/$cm$^{3}$. For the muscovite sample, the H concentration originating each from bound water and absorbed water is uniform over the entire thickness of the sample. The determined concentration $(9.43 \pm 0.75) \times 10^{21}$ H$/$cm$^{3}$ of the muscovite agrees excellently with the value of $9.36 \times 10^{21}$ H$/$cm$^{3}$ obtained from other quantitative analyses typically applied for minerals. The present results demonstrate the capability of accurate determination of H contents in materials and minerals by transmission ERDA.
