Reinhold Sellien,Helmut Sellien1) + C1., is reported as a function of coverage at 193 and 248nm and near the threshold for photoelectron emission at 280nm. The ion emission cross-section is found to be enhanced for the first molecular layer in direct contact with the substrate. The crosssection for ion emission is very low; howev

Reinhold Sellien,Helmut Sellienhat the high degree of electronic excitation present in a metal under femtosecond illumination is responsible for desorption. A model for this process involving desorption induced by multiple electronic excitations (DIMET) is presented.

We can unambiguously establish the change from a direct to a substrate-mediated excitation mechanism in the photodesorption of SO. (hν = 6.4 eV) on a quartz prism, with and without a 300 Å

Neutral species were state-selectively detected by the resonanceenhanced multiphoton ionization technique. The yields of NO, NO., CO and CO. are proportional to the first, third, third, and ~1.8th powers of laser fluence, respective

Absorption of visible or UV photons in large band gap materials can take place by multiphoton excitation [1] of valence band electrons, defects or particle inclusions [2]. The creation of an electron-hole plasma in the interaction volume of the la

(H. and OH.) ions were observed in electron-induced desorption measurements with 300 eV electrons from the bare (water-covered) (1102) surface. Sapphire surfaces were characterized with low energy electron diffract

The product kinetic energy distribution (KED) for samples irradiated with 244 nm light, for Ag. and the impurity species K. resemble the KED of Al. desorbed from Al(111) and Al/sapphire (< KE > ≈3–4 eV). However, for resonance excitation (320 nm) of the Ag adlayer, all product KEDs shift
