Structural properties of hydrogen-like ions ([formula omitted] 1–18) under quantum and classical plasma environment

Abstract

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 2L [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.
