Rotational relaxation in a 4He superfluid nanodroplet is studied adapting a quantum approach recently proposed by us. In the first theoretical study on this problem several isotopes of H2 are examined (cascade mechanism, time scale of ns, etc.).

Quantum Approach

The vibrational relaxation (VER) of a X2 molecule in a 4He superfluid nanodroplet (HeND; 0.37 K) was studied adapting a quantum approach recently proposed by us. In the first theoretical study on the VER of molecules inside HeND the I2 molecule was examined [cascade mechanism (ν → ν − 1; ν − 1 → ν − 2; …) and time scale of ns].

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.
