【 摘 要 】

We detected recurrent fluorescence (RF) in the region of visible light emitted from small carbon cluster anions C4-and C6-stored in an electrostatic ion storage ring. The observed RF decay profile for C4-is consistent to our simulation under the assignment that the RF is associated with the C2πg-X2πutransition. In addition, observation of the RF at two different wavelengths suggests that the RF band is rather broad.
