Lines corresponding to several transitions from autoionized states of single-ionized tin were identified in a laser-produced plasma generated by 10640 Å irradiation of an Sn target at a flux of 2x10¹⁰ W cmˉ². Spectra were recorded and analyzed between 2000 and 7000 Å. Theoretical analysis of Sn II was extended using relativistic Hartree-Fock calculations and configuration interactions in an intermediate-coupling scheme with the support of the Cowan code. Our calculations support the experimental value obtained by Schectman et al. in 2000 of the lifetime of 5s²5d ²D₃/₂ and the absorption oscillator strength of the resonance transition to this level at 1400.45 Å. The parametric description of 5s5p (³P⁰) nl(nl=5d,6s) of Sn II levels is improved by taking into account the far 5p³ configuration mixing effects. The results obtained in this study will allow a substantial improvement in the interpretation of the data of the ultraviolet spectrum of Sn II observed by the Goddard High Resolution Spectrograph aboard the Hubble Space Telescope.
