Alignment, Orientation, and the Beam--Foil Interaction

摘要

The aim of the study of the ion--foil interaction is to provide as complete as possible a description of the state of the outgoing beam produced when ions are transmitted through thin foils and to construct a physical model of the interaction process which can explain these results. Results for the 3p exp 1 P and 4d levels of He I are presented. These results furnish much descriptive information concerning the nature of the interaction, but not a complete model of the interaction process. They do suggest an important role for surface effects and are strongly suggestive of an important role in these processes for electron capture. 10 references. (ERA citation 04:035075)
