Grotrian diagrams of our Ba v (top), Ba vi (middle), and Ba vii (bottom) model ions. Horizontal bars indicate levels, gray lines represent radiative transitions with known f values (Tables 1–3). Our strategic Ba vi and Ba vii lines in the FUSE wavelength range (Fig. 6) are labeled with their wavelengths. The long-dashed, horizontal lines in each panel show the ionization energies of 468 000 cm-1, 573 000 cm-1, and 694 000 cm-1 of Ba v, Ba vi, and Ba vii, respectively.
