The importance of collisional coupling among high-energy pseudometastable levels of Fe II excited by Lyα.

Abstract (from CDS):

We study the effects of high-energy pseudometastable levels in modeling Fe II spectra excited by Lyα fluorescence. We demonstrate that collisional couplings between metastable- and radiative-emitting levels are of fundamental importance in the formation of the spectrum under a wide range of physical conditions that encompass most astronomical fluorescent Fe II sources. Electron-impact-induced transitions from metastable levels strengthen the overall emission spectra and, in particular, strengthen the lines that results from secondary decay after Lyα pumping, like the so-called ``1 µm lines.''
