Times Cited Count：0 Percentile：0(Optics)We have performed laser ablation of silicon in neon gas and benzene vapor. The reaction mechanism of the ablated silicon atoms with the neon atoms and benzene molecules were investigated by space- and time-resolved emission spectroscopy. The ablation in the neon gas suggested that (1) the neutral neon atoms are excited to 2pn states lying in 18-19 eV and (2) the neutral neon atoms are excited by electronic-to-electronic and translational-to-electronic energy transfer from the silicon ions. In the ablation in the benzene vapor, we found that the benzene molecules are decomposed into C2 and CH radicals by the collision with the silicon atoms.

High precision noble gas isotope analysis of groundwater is useful to estimate age and origin of groundwater. This study presents measurement of isotope ratio using a multi-collector noble gas mass spectrometer with six collectors and an auto noble gas purification instrument. The results of measurement of neon and helium in trial samples suggest that the mass spectrometer with high precision enable the noble gas isotope analysis of groundwater.
