K-shell photoionization of plasma-embedded Li-like Fe XXIV

The impact of dense plasma environment on the K-shell photoionization (PI) cross sections of ground and excited states of the plasma-embedded Li-like Fe XXIV ion is analyzed using the relativistic distorted wave method by incorporating analytical plasma screening potential. Excited state energies of target ion Fe XXV and transition probabilities for 1s2 1S0 → 1s3p 1,3P1o transitions of target ion Fe XXV are investigated at various plasma conditions. Plasma screening effects on K-threshold, auger widths, auger energy, and ionization potential depression of the Li-like Fe XXIV have also been investigated. Further, plasma screening effects on the continuum wave function of the orbitals 1s1/2, 2s1/2, and 2p3/2 of Fe XXIV have been shown. Furthermore, plasma screening effects on PI cross sections for the states 1s22s 2S1/2 and 1s22p 2P1/2,3/2o and photorecombination for the states 1s22s 2S1/2 and 1s22p 2P1/2o of Li-like Fe XXIV ion are studied. These findings will be useful in the modeling of astrophysical and laboratory plasmas.
