Abstract
Isotope ratio measurements of metallic uranium samples were carried out by linear TOF mass spectrometry in combination with laser ablation. To elimina te the problems resulting from laser plasma ion energy and spatial dispersi ons, the uranium atoms were post-ionized by the third harmonic of a Nd-YAG laser. Experimental and theoretical results of the LA-TOF performance and n on-selective photoionization of uranium atoms produced by laser ablation ar e presented. (C) 2000 Elsevier Science B.V.
