【摘要】 报道了用一束二倍频Nd:YAG激光同步抽运的脉冲染料激光系统,e型电子枪,铀原子束装置以及利用在单原子检测技术基础上发展起来的共振电离光谱和飞行时间质谱同时测量的技术,测量铀原子激发态吸收截面的饱和吸收方法。此法具有相当高灵敏度、高分辨率和强选择性的特点。更多还原

【Abstract】 This paper described saturation method for determining absorption cross sections by using a setup composed of the pulsed dye lasers system synchronously pumped by a frequency doubled Nd:YAG-Laser, e-type electron gun, apparatus for atomic beam of U, and by using the technique measuring resonant photoionization spectrum and time-of-flight mass spectrum at the same time. This method has very strong selectivity, extremely high sensitivity and resolving power, which is developed on the base of single-atom detection technology.更多还原
