The trigonometric Pöschl–Teller (PT) potential describes the diatomic molecular vibration. In this paper, we study the approximate solutions of the radial Klein–Gordon (KG) equation for the rotating trigonometric PT potential using the Nikiforov–Uvarov (NU) method. The energy eigenvalues and their corresponding eigenfunctions are calculated for arbitrary l-states in closed form. We obtain the non-relativistic limit and present some numerical results for both relativistic and non-relativistic cases.
Key words: Klein–Gordon Equation; Trigonometric Pöschl–Teller Potential; Nikiforov–Uvarov Method.
