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

The effects of the non-ideality (NI) of classical plasmas on the scattering of positron from the
ground state of hydrogen atom have been investigated by solving coupled multi-channel two …

We present a detailed analysis of the plasma-induced resonance-like atomic structures near
the ionization threshold in one-and two-photon ionization of hydrogen atom. Such …

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 carry out calculations for S-wave and P-wave resonances in e+-H scattering in weakly
coupled Debye plasma in which the interaction between two charged particles is …

An accurate theoretical expression is proposed for the atomic structure under external
confinement. The analysis is based on the tensor expression for the Breit-Pauli Hamiltonian …

Scattering of positrons from the ground state of hydrogen atoms embedded in dense
quantum plasma has been investigated by applying a formulation of the three-body collision …

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 …
