Photoionization of Trans-Fe Ions: Se IV, Se V, and Se VI
In the present study, the photoionization cross-sections are calculated for the trans-Fe ions Se IV, Se V, and Se VI over a wide energy region for ground and meta-stable states within the Dirac Atomic <i>R</i>-matrix approach (<span style="font-variant: small-caps;">darc&...

| description | In the present study, the photoionization cross-sections are calculated for the trans-Fe ions Se IV, Se V, and Se VI over a wide energy region for ground and meta-stable states within the Dirac Atomic <i>R</i>-matrix approach (<span style="font-variant: small-caps;">darc</span>). Our cross-section results, when benchmarked against the available high-resolution measurements taken at the Advanced Light Source (<span style="font-variant: small-caps;">ALS</span>) for Se IV (Ga-like) and Se VI (Cu-like) selenium ions, show good agreement over the entire photon energy investigated. The present high quality cross-section data are suitable for use in many applications in astrophysics. |
