摘要:

A convenient method is described for measuring the secondary electron ejection coefficient for thermal metastable atoms striking a metal surface, thereby permitting the absolute determination of metastable atom fluxes. Potential sources of systematic error are discussed. Results are presented for He(21S) and He(23S) metastables striking a gas‐contaminated stainless steel surface.
