Reactive Processes

A hybrid TDDFT approach was proposed to consider bimolecular reactive processes in superfluid helium nanodroplets. The Ne + Ne@(4He)N reaction was considered as the first application example. The formation of Ne2 is a complex process related to the nature of the helium density waves and their reflection from the nanodroplet surface.

Co Addition

Binary clusters have been formed by co-addition of 5,10,15,20-tetra(4-pyridyl)porphyrin (H2TPyP) and gold atoms to helium nanodroplets, and the resulting complexes are found to have different structures at different pickup orders.

Helium Nanodroplets

We study the photodissociation of the potassium atom from a superfluid helium nanodroplet upon 5s 2S or 4p 2P excitation using the time-dependent helium density functional method (He-TDDFT). The results show possible K spin–orbit relaxation.

Indium dimers (In2) solvated inside helium nanodroplets are studied with femtosecond photoelectron and photoion spectroscopy. The solvation dynamics triggered by photoexcitation of the In2 include expansion of the solvation shell and dopant ejection from the droplet, which both proceed more slowly than for In atoms. Oscillation of the solvation shell, in contrast, is similar to the case of In atoms. These processes are observed in combination with intrinsic dynamics of the molecule and set the time-frame for the dopant interaction with the quantum fluid environment.
