Quasiresonances in atom-surface collisions

چکیده
The only global autonomous system in which quasiresonant processes have been previously described is the seminal example of one atom colliding with a diatom molecule. In this work we describe classical quasiresonances in a different context, the grazing angle atomsurface collisions. While in the first system the actions related to the process correspond to the internal vibro-rotational degrees of freedom of the molecule, in this new example they turn to be the two components of the momentum of the atom parallel to the surface. We discuss the range of initial actions where quasiresonant processes arise, and suggest a new method to localize quasiresonance regions using the dwell time of the incoming atom in the vicinity of the

Molecular Dynamics Simulation of Al Energetic Nano Cluster Impact (ECI) onto the Surface
On the atomic scale, Molecular Dynamic (MD) Simulation of Nano Al cluster impact on Al (100) substrate surface has been carried out for energies of 1-20 eV/atom to understand quantitatively the interaction mechanisms between the cluster atoms and the substrate atoms. The many body Embedded Atom Method (EAM) was used in this simulation. We investigated the maximum substrate temperature Tmax and...
متن کاملd ionization: Stratified symmetrical electron emission and resonantly structured ionization continuum
We have discovered theoretically that ionization of a one-dimensional quantum well by an ultrashort subcycle ~d-like! electromagnetic pulse results in photoelectrons propagating both along the field and in the opposite direction in well-separated shells whose velocities reflect quasiresonances in the ionization continuum. For both a quantum well and a three-dimensional hydrogenlike atom, a unip...

متن کاملInteractions and dynamics in Li+Li2 ultracold collisions.
A potential energy surface for the lowest quartet electronic state ((4)A(')) of lithium trimer is developed and used to study spin-polarized Li+Li(2) collisions at ultralow kinetic energies. The potential energy surface allows barrierless atom exchange reactions. Elastic and inelastic cross sections are calculated for collisions involving a variety of rovibrational states of Li(2). Inelastic co...
متن کاملMagneto-rotation and magnetic circular dichroism of cesium atoms near a dielectric surface
The magneto-optical properties of cesium vapor near a glass surface have been studied by using selective reflection. We have observed sub-Doppler structures in the magnetorotation and magnetic circular dichroism spectra. The spectral narrowing can be explained by the transient polarization behavior of cesium atoms due to wall collisions. A simple model, which takes atom-wall collisions and the ...
