利用HCD灯进行U激光敏化荧光光谱测量

Measurement of fluorescence spectra sensitized by laser excited U atoms with HCD lamp

利用直流稳定放电的Kr-U HCD灯作为放电等离子体源,在591.54nm波长对U原子进行共振激发,在400～800nm波长范围内观察到了几百条激光敏化荧光光谱线,并由此测定了UHCD灯中相应能级集居数增量的分布。

With a CW stably discharged Kr-U HCD lamp as discharge plasma source, the U-atom was resonantly excited at the laser wavelength 591.54 nm. In the wavelength range between 400 nm and 800 nm, several hundreds of laser sensitive fluorescence lines were observed. The distribution of related level population increasemeat was measured by this method.
