9417924 Sellin This proposal calls for a study of the, "Interaction of X-Rays, Vacuum UV, and Ions with Atoms, Ions and Surfaces". It is for the study of various physical processes which occur in direct photoionization and in the related phenomena of electron emission in grazing incidence collisions of ions with clean surfaces. It proposes to compare the rates for single and double photoionization both experimentally and theoretically in He. it proposes to study the production of hollow atoms in Li and to pursue work in collaboration with Japanese co-workers on merged photon-ion beam experiments. Finally experiments on electron emission in grazing incidence ion-surface interactions will be studied. ***

9417924在这项提案中，要求研究“X射线、真空紫外光和离子与原子、离子和表面的相互作用”。它用于研究离子与清洁表面的掠入射碰撞中发生的直接光电离中的各种物理过程以及电子发射的相关现象。建议从实验和理论两个方面比较氦原子的单、双光电离速率。它提议研究锂中空原子的产生，并与日本同事合作进行合并光子-离子束实验。最后，对掠入射离子-表面相互作用中的电子发射进行了实验研究。***
