| Abstract: |
We present new calculations performed with our transfer code, Titan, with updated atomic data. In particular we show the influence of the column-density on the population of the n = 2 complex of He-like ions, those latter being widely used to provide diagnostics in optical thin plasma using the so-called x, y, z and w lines. We apply those diagnostics to optical thick photoionised plasma and compare them with the optical thin case. |
