T. Makimura et al., TIME-RESOLVED X-RAY-ABSORPTION SPECTROSCOPY FOR LASER-ABLATED SILICONPARTICLES IN XENON GAS, JPN J A P 2, 35(6A), 1996, pp. 735-737
We developed a laboratory-scale in situ apparatus for soft X-ray absor
ption spectroscopy with a time resolution of 10 ns and a space resolut
ion of 100 mu m. Utilizing this spectrometer, we have investigated the
dynamics of silicon atoms formed by laser ablation in xenon gas. It w
as found that 4d-electrons in the xenon atoms are excited through coll
ision with electrons in the laser-generated silicon plasma.
