Dynamics of Excited Sodium Atoms Attached to Helium Nanodroplets

The dynamics of laser-excited sodium atoms at the surface of helium nanodroplets has been investigated as a function of quantum state. For all cases excitation of the system leads to desorption of the sodium atom from the droplet surface. The mean kinetic ...

Translational dynamics of photoexcited atoms in 4He nanodroplets: the case of silver

Marcel Drabbels, Evgeniy Loginov, Alberto Hernando de Castro

The dynamics following the photoexcitation of Ag atoms in 4He nanodroplets via the 5p 2P1=2 ← 5s2S1=2 and 5p 2P3=2 ← 5s2S1=2 transitions has been investigated in a joint experimental and theoretical effort. It has been experimentally found that upon excita ...

Critical Landau velocity in helium nanodroplets

Marcel Drabbels, Evgeniy Loginov, Nils Benedict Brauer, Alberto Hernando de Castro

The best-known property of superfluid helium is the vanishing viscosity that objects experience while moving through the liquid with speeds below the so-called critical Landau velocity. This critical velocity is generally considered a macroscopic property ...

Spectroscopy and Dynamics of Barium-doped Helium Nanodroplets

Marcel Drabbels, Evgeniy Loginov

Excitation spectra up to the ionization threshold are reported for barium atoms located on the surface of helium nanodroplets. For states with low principal quantum number, the resonances are substantially broadened and shifted towards higher energy with r ...

Spectroscopy on Rydberg states of sodium atoms on the surface of helium nanodroplets

Marcel Drabbels, Evgeniy Loginov

One- and two-photon excitation spectra of sodium atoms on the surface of helium droplets are reported. The spectra are recorded by monitoring the photoionization yield of desorbed atoms as function of excitation frequency. The excitation spectra involving ...

Unusual Rydberg System Consisting of a Positively Charged Helium Nanodroplet with an Orbiting Electron

Marcel Drabbels, Evgeniy Loginov

Evidence is presented of an unusual Rydberg system consisting of a helium nanodroplet containing a positively charged sodium ion and an orbiting electron. Rydberg states of this system with principal quantum number n

Photoexcitation and photoionization dynamics of doped liquid helium-4 nanodroplets

Evgeniy Loginov

The photoexcitation and photoionization dynamics of sodium atoms deposited on the surface of helium nanodroplets and aromatic molecules (aniline, phenol and toluene) embedded in the interior of droplets have been investigated by a variety of spectroscopic ...

A New Sensitive Detection Scheme for Helium Nanodroplet Isolation Spectroscopy: Application to Benzene

Marcel Drabbels, Evgeniy Loginov, Andreas Braun

A new method is presented for recording excitation spectra of molecules embedded in helium nanodroplets. The method relies on the complete evaporation of the droplets following excitation of an dissolved molecule and the subsequent detection of the remaini ...

Excited State Dynamics of Ag Atoms in Helium Nanodroplets

Marcel Drabbels, Evgeniy Loginov

The excited state dynamics of silver atoms embedded in helium nanodroplets have been investigated by a variety of spectroscopic techniques. The experiments reveal that 5p 2P1/2 ← 5s 2S1/2 excitation of embedded silver atoms results almost exclusively in th ...
