| Description | Journal: Journal of Physics D: Applied Physics Reports measurements of electron emission yields of clean molybdenum surfaces under bombardment with $H^{+}$, H_{2}$^{+}$, $D^{+}$, D_{2}$^{+}$, $He^{+}$, $N^{+}$, N_{2}$^{+}$, $O^{+}$, O_{2}$^{+}$, $Ne^{+}$, $Ar^{+}$, $Kr^{+}$ and $Xe^{+}$ in the wide energy range 0.7-60.2 keV. The clean surfaces were produced by inert gas sputtering under ultrahigh vacuum. The results were compared with those predicted by a core-level excitation model. The disagreement found when using correct values for the energy levels of Mo is traced to wrong assumptions in the model. A substantially improved agreement with experiment is obtained using a model in which electron emission results from the excitation of valence electrons from the target by the projectiles and fast recoiling target atoms. |
