Ultrafast photodissociation dynamics in electronically excited CF2I2 molecules
Using the femtosecond pump-probe technique with photoion and photoelectron detection the ultrafast dissociation processes in excited CF2I2 molecules have been analyzed suggesting the dominance of a concerted thre...

Vibrational Wave Packet Propagation Dynamics in the Dissociative K3 Molecule
For the potassium trimer an electronic state around 800 nm is observed for the first time by femtosecond real-time three photon ionization (3PI) spectroscopy. The recorded temporal evolution of the one color 3...

Intensity Effects on Ionization Pathways in K2: Control of the Wave Packet Dynamics
Experimental and theoretical pump-probe studies were performed for the K2 molecule. Special molecular spectroscopic properties combined with the induced dynamics by the ’femtosecond state preparation’ allow the t...

Femtosecond Dynamics of the Ground State of Ag3
We describe a new approach which we have used to investigate small silver clusters, Agn, (n=3, 5, 7 and 9). The method starts with a beam of mass-filtered, negatively-charged clusters. These anions are subjected ...

Aerogel as a Transparent Thermal Insulation Material for Buildings
Insulating a building envelope is a very efficient method of cutting down on heating energy demand. Transparent thermal insulating systems combine both the advantages of conventional opaque insulation and the ...

Time-Resolved Secondary Emission of Free Indirect Excitons in AgBr
The relaxation behaviour of indirect exciton systems so far has been studied by analyzing the resonant secondary emission (RSE) observed under stationary optical excitation at varying photon energies in the ex...
