This research is in the general area of analytical and surface science and in the subfield of surface science. Dr. Becker will study the rates of reactions and the structure of reaction products including both molecules and ions. This research will use electron- and ion-stimulated desorption of molecules and atoms from single crystal nickel surfaces followed by nonselective photoionization. Time-of-flight mass spectrometry will then be used to detect and identify the ions formed. This research will contribute to the better understanding of the rates and mechanisms of surface catalyzed reactions.

这项研究位于分析和表面科学的一般领域以及表面科学的子场。 贝克尔博士将研究反应速率和包括分子和离子在内的反应产物的结构。 这项研究将使用单晶镍表面的分子和原子的电子和离子刺激的解吸，然后进行非选择性光电离。 然后将使用飞行时间质谱法来检测和识别所形成的离子。 这项研究将有助于更好地理解表面催化反应的速率和机制。
