Energieverteilung der von 2, 5, 10 und 15 keV He- und Ar-Ionen an Molybd�n ausgel�sten Elektronen

1966

The energy distribution of electrons ejected from Mo by He und Ar-ions of 2, 5, 10 and 15 keV has been measured by an electrostatic analyzer of the 127° cylindrical condenser type. The relative number of faster electrons grows with increasing primary energy, but the position of the maximum of the distribution curves (1.9 eV for He and 1.7 eV for Ar) is the same for ion energies of 5, 10 and 15 keV. Only for 2 keV the maximum is shifted slightly towards lower energies.
