The studies of the influence plasma environments on level structures and transition properties for highly charged ions are presented. For relativistic treatment, we implemented multiconfiguration Dirac-Fock method incorporating ion sphere (IS) model potential, in which screening is taken into account as a modified interaction potential between electron nucleus. nonrelativistic analytical solutions Schrödinger equation with two types IS screened proposed. Ritz variation used hydrogenic wave...
ABSTRACT This manuscript introduces a relativistic method to determine the electronic structure and electron collision ionization process of atoms placed in semiclassical plasma. The uses effective interaction pseudo‐potential derived for general two interacting charged particles taking into account quantum mechanical screening effects model plasma environment. Dirac equation with aforementioned is solved numerically obtain bound state continuous wave functions. starts from thus includes on...
Systematic investigations are performed for the energy levels and radiative properties selected He-like C4+, Ne8+, Ar16+, Kr34+ ions embedded in weakly coupled plasmas. For conditions which Coulomb coupling parameter is small, standard Debye model adopted to describe plasma screening effects. Within relativistic framework, modified version of Flexible Atomic Code computations carried out by considering a Debye-Hückel potential, taken into account both electron-nucleus electron-electron (e-e)...
This paper reports the development of a novel distorted wave approach based on relativistic configuration interaction theory for calculating atomic structures, radiative properties, and collision dynamics atoms or ions under external confinement. Due to its physical interpretations, Hulthén potential, valid many important areas (widely plasma environments) in physics chemistry, such as physics, solid-state nuclear particle astrophysics, is used include effect background. The Breit quantum...
Longitudinally-polarized-electron-impact excitation cross sections from the ground state to individual magnetic sublevels of excited $1s2{s}^{2}2{p}_{3/2}$($J = 2$) highly charged Be-like ions are calculated using a fully relativistic distorted-wave method.

The process of excitation highly charged Fe XXIV ion embedded in weakly coupled plasmas by electron impact is studied, together with the subsequent radiative decay. For target structure, calculation performed using multiconfiguration Dirac-Hartree-Fock method incorporating Debye-Hückel potential for electron-nucleus interaction. Fine-structure levels 1s22p and 1s2s2p configurations transition properties among these are presented over a wide range screening parameters. collision dynamics,...
The description of the plasma effect using an accurate screened potential, which is crucial for many applications physics, represents a hitherto challenge theory. Here, we present theoretical determination level delocalization and transition rate exemplary hydrogen atom immersed in plasmas. Specific forms potentials include average-atom, standard ion-sphere, those recently proposed by Shukla Eliasson [Phys. Rev.

Longitudinally polarized electron impact excitation from the ground state 1s2 to excited 1s2l (l =s,p) levels of highly charged He-like Fe24+ ions in weakly coupled hot-dense plasmas is investigated using a fully relativistic distorted-wave method. The Debye-Hückel potential used describe plasma screening. Benchmark results such as total cross sections, magnetic sublevels and circular polarizations corresponding X-ray radiations are presented. For process, show that screening has an effect...
On the basis of tensor expression for Breit-Pauli Hamiltonian and irreducible theory many-electron atoms, we have proposed a general analytical method calculating atomic structures highly charged ions under dense plasma environment. In this method, standard ion-sphere (IS) potential is used to represent interaction between charge particles. The Racah wave functions are obtained as linear combinations multi-Slater functions. angular interactions spin sums worked out using an complex systems....
