Abstract
The lifetime broadening and molecular field splitting of the sodium dimer 2p core level is studied by x-ray photoelectron spectroscopy and by Auger electron spectroscopy. The lifetime of the Na 2p core hole has been determined to be 15 +/- 8 fs, much shorter than what has previously been reported for solid sodium. The molecular field splitting of this core level has been determined to be 42 +/- 10 meV. The Auger measurements have experimentally confirmed that the sodium dimer is a good example of when the Coulomb explosion mechanism determines the spectral shape.
