Solutions of the Dirac and Schrödinger equations with shifted Tietz-Wei potential

. We solved the Dirac equation using the modified factorization method with the shifted Tietz-Wei potential model. Relativistic and non-relativistic ro-vibrational energy spectra were obtained as well as numerical solutions for different diatomic molecules ( H 2 ( X 1 ∑ g + ) , N 2 ( X 1 ∑ g + ) , a...

Description
Summary:. We solved the Dirac equation using the modified factorization method with the shifted Tietz-Wei potential model. Relativistic and non-relativistic ro-vibrational energy spectra were obtained as well as numerical solutions for different diatomic molecules ( H 2 ( X 1 ∑ g + ) , N 2 ( X 1 ∑ g + ) , and O 2 ( X 3 ∑ g - ) ). The eigenfunction for this potential has been obtained in terms of hypergeometric function. The energy variations were discussed graphically for different parameters of the shifted Tietz-Wei potential. Our results are in good agreement with the ones available in the literature.
