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…
Approximate Dirac solutions of complex -symmetric Pöschl-Teller potential in view of spin and pseudospin symmetries
Sameer M. Ikhdair, Majid Hamzavi
By employing an exponential-type approximation scheme to replace the centrifugal term, we have approximately solved the Dirac equation for spin- particle subject to the complex -sy…
Equivalence of the empirical shifted Deng-Fan oscillator potential for diatomic molecules
Majid Hamzavi, Sameer M. Ikhdair, Karl-Erik Thylwe
We obtain the bound-state solutions of the radial Schrödinger equation (SE) with the shifted Deng-Fan (sDF) oscillator potential in the frame of the Nikiforov-Uvarov (NU) method an…
Effect of Tensor Interaction in the Dirac-Attractive Radial Problem under Pseudospin Symmetry limit
Majid Hamzavi, M. Eshghi, Sameer M. Ikhdair
We approximately investigated pseudospin symmetric solutions of the Dirac equation for attractive radial potential including a Coulomb-like tensor interaction under pseudospin symm…
