We resolve an open question about the origin of the giant enhancement in the high-harmonic generation spectrum of atomic xenon around 100 eV. By solving the many-body time-dependent Schrödinger equation with all 4d, 5s, and 5p orbitals active, we truly demonstrate the enhancement results from the collective many-body excitation induced by the returning photoelectron via two-body interchannel in...

Graphene grown on an ultrathin CoSi/CoSi 2 silicide layer atop a SiC(0001) substrate and intercalated by Au was studied. Intercalation of found to occur at temperature 500 o C, it is accompanied the formation gold under graphene with stoichiometry close Si. The study electronic structure system in region (K) point surface Brillouin zone revealed quasi-freestanding character linear spectrum π st...

Aluminum nitride was analyzed by high-energy photoelectron spectroscopy using monochromatic Cr K? (5414.8 eV) radiation. The reported data include a survey spectrum and high-resolution spectra of Al 1s, 2s, 2p, N O C 1s core levels.

The multiphoton multichannel photodynamics of NO(2) has been studied using femtosecond time-resolved coincidence imaging. A novel photoelectron-photoion coincidence imaging machine was developed at the laboratory in Amsterdam employing velocity map imaging and "slow" charged particle extraction using additional electron and ion optics. The NO(2) photodynamics was studied using a two color pump-...

We report the first experimental determination of the electron affinity of gallium. The experiment was performed using the laser photodetachment electron spectrometry technique. Photoelectron kinetic energy spectra from Cu− and O− were used to calibrate the energy scale for the Ga− photoelectron energy spectra. The electron affinity was determined to be 0.43±0.03 eV. This measurement is compare...
