Abstract(in Japanese) (See Japanese page)
Abstract(in English) Measurement technique of isotopic ratio of boron by laser-induced breakdown spectroscopy has been investigated. By irradiating a Q-switched Nd:YAG laser onto the boron disk sample in a low pressure of ambient air the emission spectra of BO molecule were observed in the wavelength region from 330nm to 560nm. Each band spectrum of the ^<2>Π-^<2>Σ transition observed in the experiment was well reproduced by this calculation code. It was found that each band spectrum consists of three wide peaks and from their relative peak heights the isotopic ratios of boron can be evaluated.
