The ${\ensuremath{\beta}}^{\ensuremath{'}}$ and ${\ensuremath{\beta}}^{\ensuremath{'}\ensuremath{'}}$ satellites in the measured Cu $K{\ensuremath{\beta}}_{1,3}$ emission spectrum are shown to be due to the double-vacancy transitions $1s3{p}^{6}3{d}^{91,3}D\ensuremath{\rightarrow}1{s}^{2}3{p}^{5}3{d}^{91,3} \mathrm{PDF}$. This assignment is consistent with an earlier analysis of a highly resolved Cu $K{\ensuremath{\alpha}}_{1,2}$ spectrum. The ${M}_{2}$ and ${M}_{3}$ level widths are estimated to be 1.68 eV, in agreement with 2.0\ifmmode\pm\else\textpm\fi{}0.3 eV and 1.6\ifmmode\pm\else\textpm\fi{}0.3 eV, respectively, from photoelectron spectroscopy, and a calculated width of 2.0 eV. Comparison of the calculated double-vacancy transition array with the neighboring elements $30\ensuremath{\le}Z\ensuremath{\le}32$ suggest a similar identification to the ${\ensuremath{\beta}}^{\ensuremath{'}}$ and ${\ensuremath{\beta}}^{\ensuremath{'}\ensuremath{'}}$ satellites in their $K{\ensuremath{\beta}}_{1,3}$ spectra.
