论文摘要
水冰的核心兴趣在气相中释放出许多不同的分子和离子。研究这些解吸物种和潜在的机制可以提供有关X射线照射在冰中的影响的有用信息。我们报告了X射线诱导的许多中性，阳离子和阴离子物种从无定形固体水中解吸的详细研究。我们讨论了解吸机制，以及螺旋钻和二级电子的相对贡献（X射线诱导的电子刺激解吸）和初始兴奋（\ rev {Direct decorption}）以及光化学的作用。阴离子不仅通过与二级电子相关的过程，而且还通过直接解离的核心分子来解吸。氧离子的解吸光谱（o $^+$，哦$^+$，h $ _2 $ _2 $ o $^+$，o $^ - $，$，oh $^ - $）对他们先前报道的他们以前报道的非常低的解吸产量的新观点，用于大多数水的辐射，表明它们大部分是从$ $ oductucts的分离中，例如$ ododucts，例如$ odouducts，例如$ o。
Core-excitation of water ice releases many different molecules and ions in the gas phase. Studying these desorbed species and the underlying mechanisms can provide useful information on the effects of X-ray irradiation in ice. We report a detailed study of the X-ray induced desorption of a number of neutral, cationic and anionic species from amorphous solid water. We discuss the desorption mechanisms, and the relative contributions of Auger and secondary electrons (X-ray induced Electron Stimulated Desorption) and initial excitation (\rev{direct desorption}) as well as the role of photochemistry. Anions are shown to desorb not just through processes linked with secondary electrons but also through direct dissociation of the core-excited molecule. The desorption spectra of oxygen ions (O$^+$, OH$^+$, H$_2$O$^+$, O$^-$, OH$^-$) give a new perspective on their previously reported very low desorption yields for most types of irradiation of water, showing that they mostly originate from the dissociation of photoproducts such as H$_2$O$_2$.
