Hot, dense plasmas exhibit screened Coulomb interactions, resulting from the collective
effects of correlated many-particle interactions. In the lowest particle correlation order (pair …

Elastic scattering of electrons on a finite-temperature quantum screened potential is studied
by using the partial wave decomposition of scattering wavefunction. The influence of plasma …

The photoionization of hydrogen-like ions in n≤ 3 bound states, embedded in cold, dense
quantum plasmas, is investigated in detail. The electron energies and wave functions for the …

We have investigated the S-wave resonance states in positron-hydrogen system embedded
in dense quantum plasmas using Hylleraas-type wave functions within the framework of the …

Positronium (Ps) formation processes in collisions between positrons and alkali atoms (Li,
Na, K, Rb and Cs) in Debye plasma environments have been investigated using the …

We present two analytical methods, Taylor expansion and Gegenbauer expansion, to
efficiently and accurately calculate the two-electron screened Coulomb potential matrix …

The screening effect of dense quantum plasmas on the ground and singly excited states of
two-electron atoms are investigated by employing the explicitly correlated Hylleraas …

Formation of Rydberg atoms due to 1 s→ nlm excitations of hydrogen, for arbitrary n, l, m, by
positron impact in weakly coupled plasma has been investigated using a distorted-wave …

The effect of screening of weakly coupled plasma on positronium (Ps) formation in excited
states in the scattering of a positron from the ground state of a hydrogen atom has been …

S-wave resonance states of the positronic sodium atom (e^+ Na e+ Na) interacting with
screened Coulomb potentials (SCP) are studied. Two different SCPs are tested, namely …
