Query: Exponential Type Complex and non-Hermitian Potentials in PT-Symmetric
  Quantum Mechanics   Using the NU method [A.F.Nikiforov, V.B.Uvarov, Special Functions of
Mathematical Physics, Birkhauser,Basel,1988], we investigated the real
eigenvalues of the complex and/or $PT$- symmetric, non-Hermitian and the
exponential type systems, such as Poschl-Teller and Morse potentials.
