Analytical solutions of the DKP equation under Tietz-Hua potential in (1 + 3) dimensions

The approximate relativistic Duffin-Kemmer-Petiau equation with Tietz-Hua potential in (1 + 3) dimension for spin one particles is investigated by approximating the centrifugal term by Pekeris approximation and using parametric generalization of Nikiforov method to obtain the bound state solution. The energy eigenvalues and eigen-function is obtained in closed form.
