Electron ejection by helium metastable atoms incident on the clean and chalcogen covered Ni(100) surface
P.D. Johnson,T.A. Delchar +1 more
TL;DR: In this article, an intense, essentially photon free, helium metastable beam has been used to cause electron ejection from the clean, oxygen and sulphur covered Ni(100) surface, in a system equippeded with an AES facility to monitor surface cleanness.

The interaction of helium metastable atoms with a clean and co covered polycrystalline tungsten surface
P.D. Johnson,T.A. Delchar +1 more
TL;DR: In this paper, an investigation was made of secondary electron ejection resulting from the impact of helium metastable atoms on a clean and CO covered polycrystalline tungsten surface respectively.

Fast He atom scattering from a tungsten (100) surface
Henning B. Nielsen,T.A. Delchar +1 more
TL;DR: In this paper, a preliminary study has been carried out of the variation in backscattered intensity versus polar angle for fast (150-1000 eV) atoms incident along the 〈110〉 azimuth of a W(100) surface, both clean and oxygen covered.

Theoretical studies of fast He atom scattering from a W{100} surface
TL;DR: Theoretical calculations of the scattering of fast neutral He atoms from W{100} are presented which are directly compared to the results from recent experiments of Nielsen and Delchar as mentioned in this paper.

Angle resolved scattering and electron ejection by helium metastable atoms incident on a tungsten (110) surface
D.J. Titley,T.A. Delchar +1 more
TL;DR: In this article, angle resolved measurements have been made of the metastable scattering and electron ejection consequent upon the interaction of a thermal energy, helium metastable beam (angular divergence 24') with a clean and oxygen covered tungsten (110) surface at 300 K.
