Abstract :We solve the 3-dimensional Schrödinger equation under the Tietz potential by an approximate analytical scheme. A Pekeris-type approximation and the Nikiforov--Uvarov technique are used in the calculations to report the arbitrary-state eigenfunctions and eigenvalues and we calculate some useful expectation values of the Tietz potential using the Hellmann-Feynman theorem and obtain the oscillator strength.Keywords : Schrödinger equation (SE), Tietz potential, Nikiforov-Uvarov (NU) method, oscillator strength
