The energy redistribution processes in C60 trapped in low temp. rare gas solids have been studied using one- and two-color femtosecond pump-probe spectroscopy. The data show an ultrafast internal conversion process, followed by a slower electronic relaxati ...

The medium response of solid hydrogens to an impulsive perturbation has been studied using Rydberg excitation of an NO impurity. This leads to formation of an "electronic" bubble which corresponds to a cage radius increment of about 25%. The process has ...
A model based on fluid dynamics is proposed, which describes the dynamics of a photoinduced spherical deformation in solid hydrogen. The dynamics is driven by femtosecond excitation of the lowest A(3ss) Rydberg state of NO trapped in an H2 crystal, leading ...
Lifetime studies of the NO A2S+ (v = 0) Rydberg fluorescence in rare gas matrixes are reported. The fluorescence stems from two types of sites, red and main. The red site fluorescence shows a lifetime lengthening of 25% in Kr matrixes and 100% in Xe matrix ...
Rydberg-Rydberg transitions are induced by absorption from the lowest Rydberg state of NO A 2S+ (3ss) in Ar matrixes, which is excited by an ArF laser at 193.3 nm. The depopulation of the A(v = 0) level to higher Rydberg states is probed by depletion of it ...
Excitation of the A(3ss) Rydberg state of NO trapped in an H2 crystal leads to the electronic bubble formation around the NO impurity, resulting in an increase of 0.9 .ANG. of the ground state cage radius. Its dynamics was followed in real-time by femtosec ...
