Decay-rate power-law exponent as a link between dissociation energy and temperature
- Indium-cluster anions In−nare probed for delayed dissociation by photoexcitation in a multi-reflection time-of-flight device. In addition to prompt dissociation with below-microsecond decay constants, we observe reactionson timescales of several tens to hundreds of microseconds. These time-resolved decay-rate measurements reveala power-law behavior in time which can be traced back to the clusters’ energy distribution due to their productionby laser ablation in high vacuum. Modeling energy distributions from such a production allows us to connect thecluster-specific dissociation energy with the ensemble temperature through experimentally determined power-law exponents.
