在399nm的热蒸汽中，观察到镱原子自由结合跃迁的连续激发带为原子线的红翼。通过监测状态原子的荧光来观察分子状态的激发，这使我们能够以高灵敏度检测分子的产生。光缔合的特点是比较跃迁到原子里德伯态。荧光信号的时间谱表明，分子状态与与原子状态相关的状态预解离。
A continuous excitation band of a free-bound photoassociation transition of ytterbium atoms is observed as a red wing of theatomic line at 399 nm for a hot thermal vapor. The excitation to themolecular state is observed by monitoring fluorescence from thestate atoms, which allows us to detect the production ofmolecules with high sensitivity. The photoassociation is characterized in comparison with transitions to atomic Rydberg states. The time profile of the fluorescence signal suggests that themolecular state predissociates with states correlating to theatomic states.
