Photoionization cross section calculations of Ne-like Mo XXXIII

Highlights: • Brief description of the electron- Mo XXXIV collision models and photoionization of Mo XXXIII. • Bound target states description, level energies, and the radiative transition probabilities between them. • Comprehensive set of level specific photoionization cross sections of Mo XXXIII computed using the Breit-Pauli R-matrix method and some important characteristic features of these cross sections. • Channel coupling effects are illustrated throughout the energy ranges considered, in particular via new structure of resonances associated with 1s²2s2p⁶ target states. • Calculation covers a large photon energy range for each symmetry with 19500 energies up to 212.33 Ryd above the first ionization threshold, 1s²2s²2p^{5 2}P^o_3/2. 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 J^π = 0^± - 6^± symmetry, up to 2s²2p⁴3s (²S_1/2) threshold at 212.33 Ryd above the first ionization threshold, 1s²2s²2p^{5 2}P^o_3/2. In this article are presented cross sections for the photoionization of ground 1s²2s²2p^{6 1}S₀ and 1s²2s²2p⁵(²P^o)3p ³P₀, 1s²2s²2p⁵(²P^o)3p ¹S₀, 1s²2s2p⁶3s ¹S₀, 1s²2s²2p⁵3s(³P^o_2,1,0), 1s²2s²2p⁵3s (¹P^o₁) 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.
