Journal ArticleDOI
Shapes of leading tunnelling trajectories for single-electron molecular ionization
TL;DR: In this paper, it is shown that leading tunnelling trajectories for single-active-electron models of ionization ionization are linear in the case of short-range interactions and almost linear for long-range interaction.
Journal ArticleDOI
Multiple scattering effects on stopping power of large clusters in solids
TL;DR: In this paper, the effects on the electronic stopping power of large clusters in solids, resulting from multiple elastic scattering of each particle in the cluster by the target atoms, in the small-angle approximation, were studied.
Journal ArticleDOI
Quantum mechanics of a free particle from properties of the Dirac delta function
TL;DR: The canonical commutation relation between the momentum and position operators and the Ehrenfest theorem in the free particle case is derived solely from differentiation of the delta function and the form of the eigenfunction for the free particles as discussed by the authors.
Journal ArticleDOI
Impurity effects on chemisorption
T. Zhang,Wing-Ki Liu +1 more
TL;DR: In this paper, the influence of a substitutional impurity atom on the chemisorption properties of an adsorbate was investigated using the Green's function method. And the impurity interaction was found to be an oscillatory function of the substrate Fermi level.
Journal ArticleDOI
Coulomb explosion patterns for swift hydrogen molecular ions penetrating through solids
TL;DR: In this article, the Coulomb explosion pattern for swift H2+ ions penetrating through solids was simulated by solving the motion equations and the forces acting on the individual H+ fragments were given by the stopping force and the dynamic interacting force.
