摘要 我们测量了杂质氦固体中H和D原子的双脉冲ESEEM(电子自旋回波包络调制)谱。原子的局部环境由相邻的D2和HD分子对ESEEM信号的调制确定。我们已经测量了由于杂质氦固体内纳米团簇的聚结以及由于隧穿交换化学反应D+HD→H+D2而引起的原子环境的变化。
Abstract We have performed measurements of the two-pulse ESEEM (electron spin echo envelope modulation) spectra of H and D atoms within impurity-helium solids. The local environments of the atoms were determined from the modulation of the ESEEM signal by neighboring D2 and HD molecules. We have measured changes in the atom environments due to coalescence of the nanoclusters within the impurity-helium solids and due to the tunneling exchange chemical reaction D+HD→H+D2.
