The flexible atomic code

Abstract: We describe a complete software package for the computation of various atomic data such as energy levels; radiative transition; collisional excitation; ionization by electron impact, photoionization, autoionization; and their inverse processes radiative recombination and dielectronic capture. The atomic theoretical background and numerical techniques associated with each process are discussed in detail. Sample applications and results are presented.

“…Experimentally, much progress has been made due to the use of ion storage rings and electron-beam ion traps (EBITs) [21][22][23]. On the theory side, a number of computational approaches have been used successfully to describe DR for many simpler ions and to produce data for plasma modelling (see [24][25][26][27][28][29][30][31][32][33][34] and references therein). For more complex targets such as Au 25+ , U 28+ , or W 20+ considered in this work, conventional DR calculations underestimate the measured recombination rates, particularly at low incident-electron energy [17,35].…”

“…In this paper, we present the results of a comprehensive computation of energy levels and transition data for nineteen ions of scandium, namely Sc iii to Sc xix, utilizing the Flexible Atomic Code (Gu 2003(Gu , 2008. Several thousands of fine-structure levels and millions of transitions have been computed, many of which have been made available electronically in the form of tables.…”

“…The method has been implemented in the FAC package [23], and successfully used to calculate atomic data of high accuracy [37][38][39][40][41][42]. The key feature of the MBPT method is the partitioning of the Hilbert space of the system into two subspaces, the model space M and the orthogonal space O.…”

“…Rice et al [10] gave some calculated data for the n ≥ 3 levels in O-like Kr. Aggarwal et al [20] reported energies and oscillator strengths for the transitions among the 272 levels of the n ≤ 3 complexes using both the multiconfiguration DiracFock (MCDF) method implemented in the GRASP1 code [21,22] and the standard relativistic configuration interaction (RCI) method in the FAC package [23]. However, because of limited account for configuration interaction (CI) effects, the atomic data presented in their work, although very valuable, are not accurate enough to directly aid line identification and diagnostics in fusion plasmas.…”
