| Research Abstract |
The metastable-induced electron spectroscopy (MIES) utilizes usually beams of excited He atoms (He*) to extract the electronic structure of solid surface topmost-layer. There are several possible paths of de-excitation of He* atoms at surfaces in the MIES. It's difficult to decide the assignment of spectrum. If the variation of the incident He* velocity on the metastable de-excitation process is used, we are recognized these process in details. We produced the He* beams formed by charge exchange in He+ - alkali-metal collisions in alkali-metal vapor chamber.
