Exact solutions of the Duffin-Kemmer-Petiau equation for the deformed Hulthen potential

Using the Nikiforov-Uvarov method. an application of the relativistic Duffin-Kemmer-Petiau equation in the presence of a deformed Hulthen potential is presented for spin zero particles. We derived first-order coupled differential radial equations which enable the energy eigenvalues as well as the full wavefunctions to be evaluated by using the Nikiforov-Uvarov method that can be written in terms of hypergeometric polynomials
