N2 - EUV photoabsorption spectra of tin ions Sn II and Sn IV have been recorded using the dual laser-produced plasma (DLP) technique in the 30-65 eV region. It is known from previous studies by Lysaght et al (2005 Phys. Rev. A 72 014502), in the 30-100 eV domain, that gradual 4f contraction along the isonuclear sequence of Sn I through Sn IV results in a redistribution of the oscillator strength from the continuum to the pseudo-discrete 4d → f channels, with many intense absorption lines dominating the spectra of Sn IV. Using Hartree-Fock with configuration interaction calculations allows us to successfully account for, and permits identification of, pseudo-discrete 4d → np, nf features within the spectra of Sn II and Sn IV.
