Assignment of electronic spectra of GdF by identifying families using the f-shell Omega decomposition method

► We perform 4-componet relativistic configuration interaction calculations on GdF. ► We focus on the Omega value generated from the seven (4f) electrons. ► The CI weights are summed for each Omega-f value. ► These weights are tabulated. ► All the electronic states below 3.0 eV are analyzed by using this table.
