Resonant K? spectroscopy of solid-density aluminum plasmas
Original language description
We report here on the resonant generation of K ? emission, that is to say the production of copious K ? radiation by tuning the x-ray FEL pulse to photon energies below that of the K edge of a solid aluminum sample. The sequential absorption of multiplephotons in the same atom during the 80 fs pulse, with photons creating L-shell holes and then one resonantly exciting a K-shell electron into one of these holes, opens up a channel for the K? production, as well as the absorption of further photons.We demonstrate rich spectra of such channels, and investigate the emission produced by tuning the FEL energy to the K-L transitions of those highly charged ions that have transition energies below the K edge of the cold material. The spectra are sensitive tox-ray intensity dependent opacity effects, with ions containing L-shell holes readily reabsorbing the K ? radiation.
