Isotope separation by laser ablation. Dependence of selectivity on laser fluence
- 1. Kyoto Univ. (Japan). Faculty of Engineering
Description
In a process of isotope separation by infrared laser ablation, a Kr matrix which contains guest molecules of SF6 (32SF6 : 34SF6 = 95.02 : 4.2) is irradiated with a pulse from a TEA CO2 laser to excite 32SF6(10P(30)) or 34SF6(10P(48)) selectively. It is proved that in the case of exciting 32SF6 the excited species of 32SF6 is less emitted from the matrix than non excited 34SF6 is. The dependence of selectivity (or separation factor) on laser fluence was examined for a range of 20-80 mJ/cm2. The optimum value of fluence is around 30 mJ/cm2. (author)
