Nonrelativistic structure calculations of two-electron ions in a strongly coupled plasma environment

TL;DR: In this paper, an approach to resolve the long-drawn problem of numerical instability for evaluating two-electron integrals with an extended basis inside a finite domain is presented, and the present values of electron densities corresponding to the disappearance of different spectral lines obtained within the framework of an ion-sphere potential show excellent agreement with Orion laser experiments in Al plasma and with recent theories.
Journal ArticleDOI

and states of two electron atoms under Debye plasma screening

TL;DR: In this paper, the energy eigenvalues of two p electrons of Be 2 + ion and D o 1, 3 states due to 2 pnd configuration of Li + and Be 2+ ion in the Debye plasma environment are reported for the first time.
Journal ArticleDOI

Precise estimation of the energy levels of two-electron atoms under spherical confinement

TL;DR: In this paper, the effect of spherical confinement on the ground state of helium-like ions (Z = 1−5) and the first four (1Se) excited states for Z = 2−5 have been analyzed in detail by using correlated Hylleraas basis sets within the variational framework.
Journal ArticleDOI

2pnp (1,3Pe) states of neutral He and Li+ ions under Debye plasma screening

TL;DR: In this paper, the energy eigenvalues of doubly excited 2pnp (1Pe) (n = 3-8) and 2PNp (3Pe)(n = 2-7) bound states of a neutral helium atom and singly ionized lithium atom were estimated under weakly coupled plasma screening for the first time using an explicitly correlated Hylleraas-type basis in the framework of the Rayleigh-Ritz variational principle.
