Structural Properties Of Hydrogen-Like Ions (Z=1-18) Under Quantum And Classical Plasma Environment

A simple pure-exponential type wavefunction in the Ritz variational framework has been proposed to estimate precise eigenenergies and radial distributions of nl [n = 1-8; l = 0-7] states of L-2 [L = 0-7] symmetry of hydrogen iso-electronic ions (Z = 1-18) under classical weakly coupled plasma and dense quantum plasma environment. Critical screening parameters, beyond which the ions cease to be in a bound state, have also been estimated for both types of plasma background. (C) 2020 Elsevier Inc. All rights reserved.
