摘要
Photoabsorption by atomic Au in the 5p and 4f excitation region has been studied using the dual laser plasma DLP technique. The observed features are dominated by two prominent Fano-type resonance lines which can be attributed to 5p --> 5d and 4f --> 5d transitions of valence excited 5d(9)6s(2)(D-2(5/2)) AU followed by autoionization. The experimental results are compared to spectra calculated for the excitation of 5d(10)6s(1)(S-2(1/2)) ground and 5d(9)6s(2)(D-2(5/2), D-2(3/2)) valence-excited states within the (R)Hartree-Fock theory and the relativistic time dependent local density approximation.
