      abstract     = {We have performed inelastic scanning tunneling spectroscopy
                      (ISTS) on individual Fe atoms adsorbed on a Ag(111) surface.
                      ISTS reveals a magnetization excitation with a lifetime of
                      about 400 fs, which decreases linearly upon application of a
                      magnetic field. Surprisingly, we find that the g factor,
                      which characterizes the shift in energy of the excitation in
                      a magnetic field, is g = 3.1 instead of the expected value
                      of 2. This very large g shift can be understood when
                      considering the complete electronic structure of both the
                      Ag(111) surface state and the Fe atom, as shown by ab initio
                      calculations of the magnetic susceptibility.},
