A continuous excitation band of a free-bound photoassociation transition of ytterbium atoms is observed as a red wing of the S01P11 atomic line at 399 nm for a hot thermal vapor. The excitation to the 0u+ molecular state is observed by monitoring fluorescence from the P13 state atoms, which allows us to detect the production of Yb2 molecules with high sensitivity. The photoassociation is characterized in comparison with transitions to atomic Rydberg states. The time profile of the fluorescence signal suggests that the 0u+ molecular state predissociates with states correlating to the S01+D23 atomic states.
