Using experimental set-ups involving single photon excitation of metastable rare gas atoms Rg(mp 5 (m +1 )s ,J = 2, 0) by a pulsed frequency-doubled dye laser in conjunction with time-of-flight ion detection, we have investigated several even Rg mp 5

This contribution addresses the reactive scattering of iodomethane cluster anions off a diamond-coated silicon surface in the kinetic energy range of 1–100 eV/molecule. We report the experimental result of an impact-induced and cluster-specific che

Pulsed beams, originating from a high pressure, fast acting valve equipped with a shaped nozzle, can now be generated at high repetition rates and with moderate vacuum pumping speeds. The high intensity beams are discussed, together with the skimmer

Decay dynamics of high Rydberg states above the first ionization limit have been studied. The decay rate to the ionization continuum, due to spin orbit coupling for atoms (Ar), or coupling to the dense manifold of available rovibronic states in polya

Resonant two-color photoionization spectroscopy has been used for the first time to study a compound which exhibits an enol → keto reaction after electronic excitation. Detecting only photoelectrons with zero kinetic energy (ZEKE), we observe two e

We address some of the unique and basic features of molecular clusters, which involve (i) surface, interior, and site-selective energetics and dynamics, and (ii) the size dependence of the energetic, spectroscopic, electromagnetic, and dynamic attrib
