Thermal properties and Fisher information for diatomic molecular
Hellman-modified-Kratzer potential model
Abstract
In this paper, we solved the Schrodinger equation with Hellmann-modified
Kratzer potential using Nikiforov-Uvarov-Functional Analysis (NUFA)
method. The obtained energy is used to study the numerical results of
the ro-vibrational energy spectra for some selected diatomic molecules
and their thermodynamic properties. In addition, we also investigated
the Fisher information for three diatomic molecules and they all
satisfied the Stam-Cramer-Rao inequalities uncertainty relations.
Special cases of the potential are discussed and we compute the
numerical eigenvalue of the modified Kratzer, Kratzer-Feus and Hellmann
potentials for comparison with other analytical methods. The results of
the present study agree with the results obtained with other known
methods.
