Abstract
An investigation was made of the influence of temperature and of the f requency of the exciting radiation on the fluorescence of molecular I- 129 vapour excited by 633 nm He-Ne laser radiation. Heating of the iod ine vapour and a shift of the exciting radiation frequency by 2 GHz to ward shorter wavelengths, relative to the centre of the Ne-20 gain pro file, enhanced by almost an order of magnitude the Sensitivity of dete ction of I-129 by the laser-induced fluorescence method. The main cont ribution to the fluorescence signal came from the 6-3 P(33) absorption line.
