Double-bound equivalent of the three-body Coulomb double-continuum wave function
(American Physical Society, 2007-03)
In cross-section calculations of electron or photon double ionization processes of two-electron atoms, it is desirable to have a symmetric description of initial and final states. In this contribution, we search the doubly ...
Helium atom in a box: Doubly excited levels within the S -wave model
(American Physical Society, 2004-12)
A complete nonperturbative close-coupling solution of the helium atom in a box problem is presented by developing two numerical techniques. The first technique is the direct solution by diagonalization of the Hamiltonian, ...
Three-body molecular states of the LiH2+ system in the Born–Oppenheimer approximation
(John Wiley & Sons Inc, 2018-08)
In this work, we present a quantum mechanical treatment of the three-body (Formula presented.) molecular system in the Born–Oppenheimer (BO) approximation, were the nuclei dynamics is evaluated over the potential energy ...
Energy Loss of protons in Au, Pb, and Bi using relativistic wave functions
(American Physical Society, 2009-03)
We present a theoretical study on proton energy loss in solid targets of atomic number greater than 54. Fully relativistic wave functions and binding energies are obtained by solving numerically the Dirac equation. Ab ...
Useful dual functional of entropic information measures
(Molecular Diversity Preservation International, 2020-04-24)
There are entropic functionals galore, but not simple objective measures to distinguish between them. We remedy this situation here by appeal to Born’s proposal, of almost a hundred years ago, that the square modulus of ...
Energy loss of protons in Wolframiun using fully relativistic binding energies and wave functions, and mean excitation energies of W, Au, Pb and Bi
(American Physical Society, 2009-12)
We present a theoretical study on the energy loss of protons in wolframium by calculating target fully relativistic wave functions and binding energies. The HULLAC code is employed to obtain numerical solutions of the Dirac ...
On the applicability of the exterior complex scaling method for scattering problems including Coulombic potentials
(Springer, 2012-04-19)
We study some formal aspects of the exterior complex scaling (ECS) approach when implemented for both short and long-range potentials. In particular, we focus on the inconsistencies related to the requirement of an artificial ...
Interactions of connexins with other membrane channels and transporters
(Pergamon-Elsevier Science Ltd, 2007-05)
Cell-to-cell communication through gap junctions exists in most animal cells and is essential for many important biological processes including rapid transmission of electric signals to coordinate contraction of cardiac ...
