SiII transition probabilities measurements in a laser induced plasma

Si II lines are observed in a laser-induced plasma, generated by a laser pu lse Focused on a silicon solid target, in a xenon plus hydrogen atmosphere. They are measured when the plasma reaches local thermal equilibrium (LTE). The spectra is numerically corrected from self-absorption. Transition prob abilities of Si II Mult. (1)-(5); (8); (9); (3.01); (7.26) lines are measur ed, for the two last above-mentioned multiplets (3.01). (7.26) no prior mea surements have been previously published. For others they agree within erro r bar with previous measurements and calculations. (C) 2001 Elsevier Scienc e Ltd. All rights reserved.
