【 摘 要 】

Laser-induced electron detachment of C-6and C6H-stored in an ion storage ring was observed respectively, focusing attention onto the delayed processes with the time constants up to several milliseconds. We found the drastic difference in the decay profiles of photo-excited C-6and C6H-that is, C-6decayed much faster than C6H-. The unexpected fast decay of C-6indicates that it is governed by the radiative cooling with electronic transitions rather than vibrational nor depletion cooling.
