Scientific paper

We present a slight modification to an existing multi-level radiative transfer code that allows us to include the effects of frequency cross-redistribution (XRD) between lines sharing the same upper level. With this improved code we calculate theoretical profiles of the O I resonance triplet lines at 130 nm through a hydrostatic model of the average quiet Sun. The width of the calculated XRD profiles show good agreement with an observed spatially averaged disk-center spectrum obtained with the HRTS spectrograph. This is in stark contrast to profiles calculated with complete frequency redistribution (CRD) and ordinary partial frequency redistribution (PRD), which have Lorentzian wings that are too broad. We find deep central reversals, contrary to most observed profiles, but note that this discrepancy is to a large degree the result of limited instrumental spectral resolution.
