Title: Excitation energies, radiative and autoionization rates, dielectronic satellite lines, and dielectronic recombination rates for excited states of Rb-like W from Kr-like W [Relativistic atomic data for Rb-like tungsten]

Abstract

Energy levels, radiative transition probabilities, and autoionization rates for [Ni]4s24p6nl, [Ni]4s24p54l'nl, [Ni]4s4p64l'nl,[Ni]4s24p55l'nl, and [Ni]4s4p66l'nl states in Rb-like tungsten (W37+) are calculated using the relativistic many-body perturbation theory method (RMBPT code) and the Hartree–Fock relativistic method (COWAN code). Autoionizing levels above the [Ni]4s24p6 threshold are considered. It is found that configuration mixing among [Ni]4s24p54l'nl and [Ni]4s4p64l'nl plays an important role for all atomic characteristics. Branching ratios relative to the first threshold and intensity factors are calculated for satellite lines, and dielectronic recombination (DR) rate coefficients are determined for the [Ni]4s24p6nl singly excited states, as well as the [Ni]4s24p54dnl, [Ni]4s24p54fnl, [Ni]4s4p64dnl, [Ni]4s24p64fnl, and [Ni]4s24p55l'5l doubly excited nonautoionizing states in Rb-like W37+ ion. Contributions from the [Ni]4s24p64fnl, [Ni]4s24p55l'nl, and [Ni]4s24p56l'nl doubly excited autoionizing states are evaluated numerically. The high-n state (with n up to 500) contributions are very important for high temperatures. These contributions are determined by using a scaling procedure. Synthetic dielectronic satellite spectra from Rb-like W are simulated in a broad spectral range from 8 to 70 Å. These calculations provide highly accurate values for a number of W37+ properties useful for a variety of applications including for fusion applications.
