      abstract     = {We exploit the decoherence of electrons due to magnetic
                      impurities, studied via weak localization, to resolve a
                      long-standing question concerning the classic Kondo systems
                      of Fe impurities in the noble metals gold and silver: which
                      Kondo-type model yields a realistic description of the
                      relevant multiple bands, spin, and orbital degrees of
                      freedom? Previous studies suggest a fully screened spin S
                      Kondo model, but the value of S remained ambiguous. We
                      perform density functional theory calculations that suggest
                      S = 3/2. We also compare previous and new measurements of
                      both the resistivity and decoherence rate in
                      quasi-one-dimensional wires to numerical renormalization
                      group predictions for S = 1/2, 1, and 3/2, finding excellent
                      agreement for S = 3/2.},
