Double ionization of neon with orthogonally polarized two-color (OTC) laser fields is investigated using coincidence momentum imaging. We show that the two-electron emission dynamics in nonsequential double ionization can be controlled by tuning the subcycle shape of the electric field of the OTC pulses. We demonstrate experimentally switching from correlated to anticorrelated two-electron emis...
The individual isotopes of neon in energetic solar flare particles have been clearly resolved with arms mass resolution of 0.20 amu. We find 20Ne/22Ne = 7.6 ( +2.0, -1.8) and 21Ne/22Ne < 0.11 in the 11-26 MeV per nucleon interval. This isotopic composition is essentially the same as that of meteoritic planetary neon-A and is significantly different from that of the solar wind. Subject headings:...
We present an ab initio approach for the computation of the magnetic susceptibility χ of insulators. The approach is applied to compute χ in diamond and in solid neon using density functional theory in the local density approximation, obtaining good agreement with experimental data. In solid neon, we predict an observable dependence of χ upon pressure. 75.20.-g, 71.15.-m, 71.15.Mb Typeset using...
The dynamics of two-dimensional solid neon is investigated within the self-consistent phonon theory. Phonon frequencies and lifetimes and the one-phonon dynamic form factor are evaluated as a function of temperature and lattice spacing in the self-consistent harmonic approximation with the cubic anharmonic term added. Two-dimensional solid neon is found to be highly anharmonic. It becomes mecha...
In this deliverable, we report on several evaluation experiments which aim to demonstrate the synergies arising from a combination of ontology design patterns and ontology learning techniques. Furthermore, we present a novel method for ontology refinement, i.e. the semi-automatic acquisition of complex domain-range restrictions, and its evaluation on the well-known SWRC ontology. A variant of t...
This work describes the first observations of the ionisation of neon in a metastable atomic state utilising a strong-field, few-cycle light pulse. We compare the observations to theoretical predictions based on the Ammosov-Delone-Krainov (ADK) theory and a solution to the time-dependent Schrödinger equation (TDSE). The TDSE provides better agreement with the experimental data than the ADK theor...
Infrared spectra of the CH(3)Cl:NO complex isolated in solid neon have been investigated. Most of the vibrational modes of the complex have been detected. The weak interaction between NO and CH(3)Cl in CH(3)Cl:NO is responsible for small shifts of the vibrational mode frequencies of both CH(3)Cl and NO molecules. The measured shifts range between -3.2 and + 3.8 cm(-1). On the basis of DFT calcu...
Two predominant currents, the warm Kuroshio Current and the cold Oyashio Current, meet in the Northwest Pacif ic Ocean. The interaction of these two currents between the subtropical and subarctic fronts forms a transition region (Roden, 1991). The dynamic of the physical oceanographic structures in this region, including meandering eddies and frontal zones, results in a highly productive habita...
