Abstract The ground state energy of a helium atom inside spherical multilayer quantum dot as function the atomic impurity location has been calculated. is modeled by core/shell/well/shell structure using parabolic confinement. Configuration Interaction method and Diffusion Monte Carlo have used to solve Schrödinger equation. Results obtained showed that lowest configuration depends on size different layers agreement between results indicates approach here would be suitable compute excited...
Abstract The problem of the stability a confined atom when it is extracted from confining cavity has been investigated, modeled by spherical hard wall potential. ionization probability released confinement obtained. dependence on radius and quantum numbers initial state studied. density function energy ejected electron obtained for different cases considered. oscillatory structure this distribution function, with principal maximum located in neighborhood minima very close to zero elucidated....
The problem of the stability hydrogen atom when it is released from a confining environment studied. analysed in terms excitation and ionisation probabilities final state for different initial states. A spherical cavity finite barrier height v0 with inner radius r0 thickness Δ nuclear position at its centre has been considered. probability presents sharply peaked, non-symmetric local maxima as function confinement size. This behaviour related to energy confined that several minima kink-like...
In this study, we address the problem of a C60 endohedrally confined hydrogen molecule through configuration-interaction approach to electronic dynamics. Modeling confinement by means combination two Woods-Saxon potentials, analyze stability system as function nuclei position behavior spectrum. After studying convergence different partial wave expansions, one related molecular Coulomb centers and other off-centering well, found that second provides more accurate description system....
Abstract In this work we studied the problem of stability confined atoms when they are released from confinement. We analyzed Hydrogen atom inside a cage modelled by square-well potential, in particular effects size on energy and electronic structure atom, considering different internal radii confining cage. Starting wave function, clarified effect probability transition between states, characterized term both, ionization to bound state free atom. The values atomic properties calculated...
