The photoabsorption spectrum of an indium laser produced plasma

The photoabsorption spectrum of In II has been recorded in the 18-33 eV region using the dual laser plasma (DLP) technique. Transitions from the 4d(10)5s(2) ground state dominate the In n spectrum with some contribution from the metastable P-3(2), P-3(1) and P-3(0) levels of the excited 4d(10)5s5p configuration also observed. Transitions were identified by comparison with values obtained from multiconfiguration Hartree-Fock calculations.
