Zusammenfassung

We have investigated the radiative cooling of initially hot Al⁻₄ and Al⁻₅ cluster anions during storage in a cryogenic ion beam trap at an ambient temperature of <15 K. By applying a statistical rate model to the ions' measured delayed detachment rate following excitation with a laser, we have obtained their vibrational temperature as a function of cooling time. The temperature curves for Al⁻₄ suggest that the vibrational cooling slows down considerably once the ion reaches approximately room temperature. This suggests the participation of transitions from recently found low-lying electronic states of the anion in the cooling process, prior to reaching approximately room temperature. The experimental results for Al⁻₅ suggest slightly slower radiative cooling than for Al⁻₄.
