WKB wave functions are expected to be accurate approximations of exact quantum
mechanical wave functions mainly near the semiclassical limit of the quantum mechanical …

In this work, we studied the bound states and quantum theoretic-information measurements

The energy levels of the Klein–Gordon equation in hyper-radial space under the Deng-Fan
potential energy function are studied by the SWKB and WKB approximation methods. We …

We find a proper quantization rule,∫ x A x B k (x) dx-∫ x 0A x 0B k 0 (x) dx= nπ, where n is
the number of the nodes of wave function ψ (x). By this rule the energy spectra of a solvable …

In this paper, we demonstrated that the multiple turning point problems within the framework
of the Wentzel‐Kramers‐Brillouin (WKB) approximation method can be reduced to two …

We obtained, by using the proper quantization rule, the approximate solutions of the
Schrödinger equation with Manning-Rosen plus Hellmann potential for any l-state …

By employing the improved Greene–Aldrich approximation scheme to deal with the
centrifugal term, we solve approximately the Klein–Gordon equation with the improved …

In this work, we applied the Nikiforov-Uvarov (NU) method to calculate the bound state
energies for two diatomic molecules such as Carbon (II) Oxide (CO) and Scandium Flouride …

The energy spectrum of the radial Schrodinger equation with the molecular Deng Fan
potential has been obtained through the WKB approximation scheme. The radial WKB …
