Nonrelativistic shifted-l expansion technique for three- and two-dimensional Schrodinger equation
Omar Mustafa, Thabit Barakat
The shifted-l expansion technique (SLET) has been developed to get eigenvalues of Schrodinger equation in three (3D) and two dimensions (2D). SLET simply consists of 1/\bar{l} as a…

Relativistic shifted-l expansion technique for Dirac and Klein-Gordon equations
Omar Mustafa, Thabit Barakat
The shifted-i expansion technique (SLET) is extended to solve for Dirac particle trapped in spherically symmetric scalar and/or 4-vector potentials. A parameter λ=0,1 is introduced…

Exact energy eigenvalues of the generalized Dirac-Coulomb equation via a modified similarity transformation
Omar Mustafa, Thabit Barakat
With the aid of a modified similarity transformation we obtained exact energy eigenvalues of the generalized Dirac-Coulomb equation. This equation consists of the time component of…
