Exact solutions of a spatially-dependent mass Dirac equation for Coulomb field plus tensor interaction via Laplace transformation method
Mahdi Eshghi, Sameer M. Ikhdair
The spatially-dependent mass Dirac equation is solved exactly for attractive scalar and repulsive vector Coulomb potentials including a tensor interaction potential under the spin…
Approximate -state Solutions to the Dirac Mobius Square-Yukawa and Mobius Square-quasi Yukawa Problems under Pseudospin and Spin Symmetry limits with Coulomb-like Tensor Interaction
Akpan N. Ikot, E. Maghsoodi, Akaninyene D. Antia +2
In this paper, we present the Dirac equation for the Mobius-square-Yukawa potentials including the tensor interaction term within the framework of pseudospin and spin symmetry limi…
Exact S-Wave Solution of the Trigonometric Poschl-Teller Potential
M. Hamzavi, A. A. Rajabi
The trigonometric Pöschl-Teller (PT) potential describes the diatomic molecular vibration. By using the Nikiforov-Uvarov (NU) method, we have obtained the exact analytical s-wave s…
The Rotation-Vibration Spectrum of Diatomic Molecules with the Tietz-Hua Rotating oscillator
M. Hamzavi, A. A. Rajabi, K. -E. Thylwe
The Tietz-Hua (TH) potential is one of the very best analytical model potentials for the vibrational energy of diatomic molecules. By using the Nikiforov-Uvarov (NU) method, we hav…
Approximate analytical solution of the Yukawa potential with arbitrary angular momenta
M. Hamzavi, M. Movahedi, K. -E. Thylwe +1
The Yukawa potential is often used to compute bound-state normalizations and energy levels of neutral atoms. By using the generalized parametric Nikiforov-Uvarov (NU) method, we ha…
Relativistic new Yukawa-like potential and tensor coupling
Sameer M. Ikhdair, Majid Hamzavi
We approximately solve the Dirac equation for a new suggested generalized inversely quadratic Yukawa (GIQY) potential including a Coulomb-like tensor interaction with arbitrary spi…
