Time-resolved extreme ultraviolet photoabsorption spectra of a manganese plasma have been recorded using the dual laser plasma technique. The 43-73 eV photon energy range is dominated by the 3p-3d giant resonance and to a lesser extent the 3p-4s resonances in both Mn{sup 2+} and Mn{sup 3+}, recorded at interplasma time delays of 80 and 30 ns, respectively. These experimentally observed resonances are well reproduced by synthetic spectra calculated using the Hartree-Fock method. The synthetic spectra allow for absorption from excited states of the Mn{sup 2+} and Mn{sup 3+} ions.
