Abstract
The lifetime of a negative ion resonance in the condensed phase and it s impact on deposition of energy are investigated as a function of the resonance energy. The variation in the energy deposited, which can be measured in situ as an energy modulation of the vibrational scattered intensities, is shown to correlate with the inverse of the density of free electron states in the host medium. As an experimental model, we studied O-2 embedded in an Ar matrix.
