Abstract

Lines in the extreme ultraviolet region involving the $3 d {}^{2}D, 4 p {}^{2}P, 5 s {}^{2}S, 6 s {}^{2}S$ , and several $nf {}^{2}F$ terms have been identified in the spectra of Mn VII and Fe VIII. In Cr VI the first member of the $3 d {}^{2}D - n f {}^{2}F$ series has been found. These spectra have been photographed with a twenty-one foot grazing incidence vacuum spectrograph. Identification was facilitated by the use of constant second difference displaced frequency diagrams.
