In this study, an approximate solution of the Schr?dinger equation for q-deformed Hulthen-quadratic exponential-type potential model within framework Nikiforov?Uvarov method was obtained. The bound state energy and corresponding eigenfunction spectrum is applied to study H2, HCl, CO LiH diatomic molecules. effect deformation parameters other on spectra system were graphically numerically analyz...

We derive the Christoffel-Geronimus-Uvarov transformations of a system of bi-orthogonal polynomials and associated functions on the unit circle, that is to say the modification of the system corresponding to a rational modification of the weight function. In the specialisation of the weight function to the regular semi-classical case with an arbitrary number of regular singularities {z 1 ,. .. ...

In this research, the radial Schrodinger equation for a newly proposed screened Kratzer-Hellmann potential model was studied via conventional Nikiforov-Uvarov method. The approximate bound state solution of obtained using Greene-Aldrich approximation, in addition to normalized eigenfunction new both analytically and numerically. These results were employed evaluate rotational-vibrational partit...
