Photoionization cross section calculations of Ne-like Mo XXXIII

Abstract

Within the framework of Breit Pauli R-matrix approach, a close-coupling calculation has been carried out for the process of photoionization of ground and excited states of Ne-like Mo XXXIII ion. The calculation includes 60 fine-structure levels and 15 parities for the target states. Level specific photoionization cross sections are computed for all levels at a fine energy mesh of 10−5 scaled Ryd, with 19500 energies for each Jπ = 0± - 6± symmetry, up to 2s22p43s (2S1/2) threshold at 212.33 Ryd above the first ionization threshold, 1s22s22p5 2Po3/2. In this article are presented cross sections for the photoionization of ground 1s22s22p6 1S0 and 1s22s22p5(2Po)3p 3P0, 1s22s22p5(2Po)3p 1S0, 1s22s2p63s 1S0, 1s22s22p53s(3Po2,1,0), 1s22s22p53s (1Po1) excited states. To explore the role of particle-hole, channels coupling and electron-electron correlation effects on the photoionization cross sections we have compared two calculation models, namely 8-target basic configurations and 5-target basic configurations, with and without 2s2p53l target states included into the model. Effects are highlighted in the photoionization cross section behavior of the excited of 2s2p63s of Mo XXXIII.We believe that this is the first such calculation for this ion to obtain the photoionization cross section and results are important for the modeling and diagnostics of laboratory and astrophysical plasmas.
