The photoabsorption spectrum of a tin laser-produced plasma has been recorded in the 23-33 eV region using the dual laser plasma technique. 4d→5p transitions from the 4d105s25p ground state of Sn II and from the 4d105s2 ground and 4d105s5p excited states of Sn III were observed and new features identified with the aid of multiconfiguration Hartree-Fock calculations. The relative intensities of transitions in Sn III indicate a departure from local thermodynamic equilibrium conditions in the absorbing plasma.
