- This document describes the calculations I have carried out to synthesize spectra for test cases Ar1, Ge1, Ba1 and Au1. First, a brief description of how HULLAC generates atomic data is presented. Next, the implementation of those data in a collisional-radiative (CR) model is described. Two approaches are taken: First, the HULLAC data are entered into the CR rate matrix, and the relative populations of each ion charge state as given by an off-line Monte Carlo calculation are used to constrain the resulting level populations. Alternatively, the HULLAC data-filled CR rate matrix is inverted with out constraining the relative ion populations; the resulting average ion charge < Z > is significantly different between the two calculations. My resulting b-b, b-f and f-f emission spectra are presented in figures.
