Abstract

The optical emission a from laser produced plasma generated by 1064 nm irradiation of Sn/Pb alloys targets at a flux of 2∙10¹⁰ W cm⁻² was recorded and analyzed between 200 and 700 nm. The Local Thermodynamic Equilibrium (LTE) conditions and plasma homogeneity have been checked. The analysis of Sn II was checked, with the support of parametric studies of the mixed configurations in both parities, by means of a self-consistent-field method to generate one-electron orbitals. The parametric description of the 5s5p² configuration is improved by taking into account 5s²5d, 5s²6d and 5s²7d mixing effects. Eigenfunctions were used to derive theoretical values of the transition probabilities. Experimental transition probabilities for 36 lines of Sn II arising from the 5s²ns, 5s2np, 5s²nd, 5s²nf, and 5s5p² configurations of Sn II have been determined. Some values have been compared with the available data in the literature and are in a good agreement. The coincidence between several experimental and theoretical transition probabilities obtained in this work is remarked.
