We have obtained.approximate bound.state solutions of Schröd.nger wave equation with mod.fied.quad.atic Yukawa plus q-d.formed.Eckart potential Using Parametric Nikiforov-Uvarov (NU) method. However, we obtained.numerical energy eigenvalues and.un-normalized.wave function using confluent hypergeometric function (Jacobi polynomial). With some mod.fications, our potential red.ces to a well-known potential such as Poschl-Teller and.exponential inversely quad.atic potential. Numerical bound.state energies were carried.out using a well-d.signed.Matlab algorithm while the plots were obtained.using origin software. The result obtained.is in agreement with that of the existing literature.

Approximate bound.state solutions of spinless particles with a special case of equal scalar and.vector mod.fied.generalized.Hulthen potential has been obtained.und.r the massive Klein-Gord.n equation. The energy eigenvalues and.the correspond.ng wave functions expressed.in terms of a Jacobi polynomial are also obtained.using the parametric generalization of the Nikiforov-Uvarov （NU） method. Und.r limiting cases our result are in agreement with the existing literature. Our results could.be used.to stud. the interactions and.bind.ng energies of the central potential for d.atomic molecules in the relativistic framework which have many applications in physics and.some others related.d.sciplines.

The bound.state solutions of the Schr?d.nger equation with generalized.inverted.hyperbolic potential using the Nikiforov-Uvarov method.are reported. We obtain the energy spectrum and.the wave functions with this potential for arbitrary l-state. It is shown that the results of this potential red.ced.to the stand.rd.potentials—Rosen-Morse, Poschl-Teller and.Scarf potential as special cases. We also d.scussed.the energy equation and.the wave function for these special cases.
