Interpretation of the spectrum of SnII: Experimental and theoretical transition probabilities

The optical emission a from laser produced plasma generated by 1064 nm irra diation of Sn/Pb alloys targets at a flux of 2.10(10) W cm(-2) was recorded and analyzed between 200 and 700 nn. The Local Thermodynamic Equilibrium ( LTE) conditions and plasma homogeneity have been checked. The analysis of S n II was checked, with the support of parametric studies of the mixed cofig urations in both parities, by means of a self-consistent-field method to ge nerate one-electron orbitals. The parametric description of the 5s5p(2) con figuration is improved by taking into account 5s(2)5d, 5s(2)6d and 5s(2)7d mixing effects. Eigenfunctions were used to derive theoretical values of th e transition probabilities. Experimental transition probabilities for 36 li nes of Sn II arising from the 5s(2)ns, 5s(2)np, 5s(2)nd, 5s(2)nf, and 5s5p( 2) cofigurations of Sn II have been determined. Some values have been compa red with the available data in the literature and are in a good agreement. The coincidence between several experimental and theoretical transition pro babilities obtained in this work is remarked.
