Type: dataset
Abstract: Description of Data for: "5p and 4f Photoabsorption in Third r-process Peak Elements, Ir, Pt, and Au" This dataset contains the experimental and synthetic photoabsorption data used to generate the figures in the above-titled publication. No modifications have been made to the original file structure. The data is organized as follows: Experimental Data Files Filename format:YYYY_MM_DD_ _Data.txt These files contain experimentally measured photoabsorption spectra. Each file consists of two columns: Column 1: Photon energy (in electron volts, eV) Column 2: Absorbance (calculated as described in the Methods section of the paper) The date prefix indicates the day of data acquisition: 2023_07_18: Iridium (Ir) 2023_07_28: Platinum (Pt) 2023_07_19: Gold (Au) Each file corresponds to a specific inter-plasma time delay (dT), with increasing ID numbers reflecting increasing delay times. For Ir data, the delay times are: ID = 46: 20 ns Followed by 35, 50, 100, 250, and 350 ns in order of increasing file ID. Platinum and gold datasets follow a similar naming structure, but do not include a 20 ns delay dataset, as these data were not included in the publication. Synthetic Cross-Section Data (Iridium Only) Filename format:Ir _ eV.txt is a Roman numeral indicating the ionisation stage (e.g., I = Ir⁰, II = Ir⁺, III = Ir²⁺, etc.) is the modeled electron temperature in eV These files contain synthetic cross-sections for iridium ions, derived from calculations using the Cowan suite of atomic codes, as detailed in the paper. Each file consists of nine columns, representing intensity (in arbitrary but consistent units) for the following transition families: Non–LS-allowed transitions 5p → 6s 5p → 7s 5p → 5d 5p → 6d 5p → 7d 4f → 5d 4f → 6d 4f → 7d These intensities are paired with a single shared energy scale (in eV), which can be retrieved from any of the Ir experimental data files beginning with 2023_07_18_. Please refer to the publication for further details on data interpretation, modeling techniques, and spectral assignments.
