On spectroscopic structure of two interacting electrons in a quantum dot
Omar Mustafa
The shifted 1/N expansion technique, used by El-Said (Phys. Rev. B 61, 13026 (2000)), to study the relative Hamiltonian of two interacting electrons confined in a quantum dot, is i…

Spectra of 2D H-donors in magnetic field and their Zeeman splitting
Maen Odeh, Omar Mustafa
The pseudoperturbative shifted - expansion technique PSLET is employed to study the spectra of 2D H-donors in magnetic field. The Zeeman effect is investigated and results are…

On the quasi - exact solvability of a singular potential in D - dimensions; confined and unconfined
Omar Mustafa
The D -dimensional quasi - exact solutions for the singular even - power anharmonic potential are reported. We show that whilst Dong and Ma's [5] quasi…
