Abstract

The ejected-electron spectra of europium arising from autoionising and Auger transitions in Eu I and Eu II following excitation by electron impact have been measured in the energy region from 0 to 27 eV; incident-electron energies were in the range from 20 to 500 eV. 151 spectral features are tabulated and excitation functions are reported for a number of autoionising and Auger transitions. The chemi-ionisation electron spectrum of europium atoms reacting with oxygen and water vapour is reported in the electron energy region from 0 to 1.5 eV.
