Elimination of spurious oscillations on photoemission spectra
Martín Barlari, Diego G. Arbó, María Silvia Gravielle +1
We present a method for accurately computing transition probabilities in one-dimensional photoionization problems. Our approach involves solving the time-dependent Schrödinger equa…
Decoherent phonon effects in fast atom-surface scattering
L. Frisco, M. S. Gravielle
Understanding the influence of phonon-mediated processes on grazing-incidence fast atom diffraction (GIFAD) patterns is relevant for its use as a surface analysis technique. In thi…
Terrace effects in grazing-incidence fast atom diffraction from a LiF(001) surface
L. Frisco, M. S. Gravielle
The effect produced by surface defects on grazing-incidence fast atom diffraction (GIFAD) patterns is studied by considering the presence of terraces in a LiF(001) sample. For heli…
The atomic ionization, capture, and stopping cross sections by multicharged ions satisfy the Benford law
J. E. Miraglia, M. S. Gravielle
The applicability of the Benford law for different data sets of atomic cross sections by ion impact is studied. We find that the data sets corresponding to theoretical ionization a…
Thermal effects on helium scattering from LiF(001) at grazing incidence
L. Frisco, M. S. Gravielle
Grazing-incidence fast atom diffraction (GIFAD) is an exceptionally sensitive method for surface analysis, which can be applied not only at room temperature but also at higher temp…
Phonon contribution in grazing-incidence fast atom diffraction from insulator surfaces
L. Frisco, M. S. Gravielle
We study the effect of crystal lattice vibrations on grazing-incidence fast atom diffraction (GIFAD) from insulator surfaces. To describe the phonon contribution to GIFAD we introd…
