The total ion and/or electron yield spectra of rare gases Xe, Kr, and Ar have been recorded around the 4${\mathit{d}}^{\mathrm{-}1}$, 3${\mathit{d}}^{\mathrm{-}1}$, and 2${\mathit{p}}^{\mathrm{-}1}$ ionization thresholds, respectively, with very high photon energy resolution at the Finnish beam line at the MAX I storage ring. Linewidths of the excited states are determined for higher excitations than earlier. The widths are observed to differ slightly for each core-excited state. © 1996 The American Physical Society.
