The Semi-Relativistic Equation Via the Shifted-l Expansion Technique
T. Barakat
The semi-relativistic equation is cast into a second-order Schrodinger-like equation with the inclusion of relativistic corrections up to order (v/c)^2. The resulting equation is s…
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…
Perturbed Coulomb potentials in the Klein-Gordon equation via the shifted-1 expansion technique
Thabit Barakat, Maen Odeh, Omar Mustafa
A shifted - l expansion technique is introduced to calculate the energy eigenvalues for Klein-Gordon (KG) equation with Lorentz vector and/or Lorentz scalar potentials. Although it…
