Abstract
The effect of He adsorption on the photoelectron yield from the solid Ne subjected to VUV radiation is studied. Electron emission is measured using cyclotron resonance of free electrons. The bulk He impurity in Ne is found to have negligible effect on the yield. The results of the study suggest that the quenching of emission by He flow fed to a low temperature substrate during Ne condensation is attributable to He atoms adsorbed on the Ne surface. A model is proposed for the surface sites responsible for ejection of electrons.
