Název v původním jazyce

Photodissociation of Hydrogen Iodide on the Surface of Large Argon Clusters: The Orientation of the Librational Wave Function and the Scattering from the Cluster Cage

Popis výsledku v původním jazyce

A new set of photodissociation experiments and simulations of HI on Ar_n clusters with an average size n=139 has been carried out for different laser polarizations. The doped clusters are prepared by a pick-up process. The hydrogen halide molecule is then photodissociated by a UV laser pulse and the outgoing H fragment is ionized by resonance enhanced multi-photon ionization (REMPI) in a (2+1)excitation scheme within the same laser pulse at a wavelength of 243 nm. The measured time-of-flight spectra aretransformed into hydrogen kinetic energy distributions. They exhibit a strong fraction of caged H atoms at zero kinetic energy and peaks at the unperturbed cage exit for both spin-orbit channels nearly independent of the polarization. At this dissociation wavelength the bare HI molecule exhibits a strict state separation, with a parallel transition to the spin orbit excited state and perpendicular transitions to the ground state. The experimental results molecular simulation techniques.
