Bombardment Induced Surface Chemistry in Energetic Particle Mass Spectrometries

这一奖项是汉利博士化学博士后奖学金的起始拨款增量，以支持他在伊利诺伊大学芝加哥分校的研究。汉利博士研究的重点是使用精密的表面光谱仪来研究高能粒子与表面的相互作用。这些实验将研究高能离子和原子轰击引起的分子在表面上的化学反应。振动和其他非破坏性表面光谱将用于将轰击引起的表面反应与二次离子、二次中性和快速轰击质谱学观察到的分子质谱相关联。这些实验将在超高真空条件下由气相沉积在单晶表面形成的吸附表面、有机固体和多组分表面的模型上进行。还将研究弹丸荷电状态和化学的作用。这些实验将试图确定导致二次分子离子和中性粒子抛射的基本物理过程，最终导致对通常由高能粒子轰击探测的真实系统的质谱学的更好解释。

This award is made as the starter grant increment of Dr. Hanley's Postdoctoral Fellowship in Chemistry Award in support of his research at the University of Illinois at Chicago. The thrust of Dr. Hanley's research is the use of sophisticated surface spectroscopies to examine the energetic particle-surface interaction. The experiments will investigate chemical reactions of molecules on surfaces induced by energetic ion and atom bombardment. Vibrational and other non-destructive surface spectroscopies will be used to correlate bombardment induced surface reactions with molecular mass spectra observed by secondary ion, secondary neutral and fast bombardment mass spectrometry. These experiments will be performed on models of adsorbate-covered surfaces, organic solids, and multicomponent surfaces formed by vapor deposition on single crystal surfaces under ultrahigh vacuum conditions. The role of projectile charge state and chemistry will also be examined. These experiments will attempt to determine the basic physical processes leading to ejection of secondary molecular ions and neutrals ultimately leading to an improved interpretation of mass spectra of real systems typically probed by energetic particle bombardment.
