Fluorescence of iodine-127 and iodine-129 isotopes excited by radiation of copper vapor laser (510.6 nm)

Abstract

The paper deals with the study of 127I2, 127I129I and 129I2 fluorescence excited by radiation of a copper vapor laser at 510.6 nm. Iodine molecule absorption lines, resonant at the wavelength of laser radiation, were identified. The obtained results were compared to those obtained while exciting fluorescence with lasers radiating at wavelengths 578.2 and 532 nm. It was shown that copper vapor lasers with a wavelength of 510.6 are promising for performing high-sensitive real-time detection of molecular iodine-129 in gaseous media. The obtained results may be used for developing totally new cost-effective and environmentally friendly technologies of electricity generation, based on fast reactors, which is extremely important for providing humanity with environmentally friendly generated electric energy.
