<p>In this work, we develop a phase space formulation of quantum mechanics to investigate the inversely quadratic Hellmann-Kratzer (IQHK) potential, with the aim of simultaneously constructing the Wigner distribution and the corresponding characteristic functions. By employing Weyl transformations, we establish two independent computational approaches, each yielding explicit and generalized analytical expressions for higher-order moments and momentum. In addition, we derive a generalized analytical formulation of the momentum operator and establish a corresponding generalized expression of Heisenberg’s uncertainty principle, explicitly dependent on the quantum numbers <i>n</i> and <i>L</i>. This constitutes a novel and complementary contribution to the study of the IQHK potential. Furthermore, the key transformation employed in phase space enabled us to derive a generalized analytical expression for the energy levels <InlineEquation ID="IEq1"> <EquationSource Format="TEX">\(E_{n,L}\)</EquationSource> <EquationSource Format="MATHML"><math> <msub> <mi>E</mi> <mrow> <mi>n</mi> <mo>,</mo> <mi>L</mi> </mrow> </msub> </math></EquationSource> </InlineEquation>. These energy levels are numerically evaluated and exhibit excellent agreement with previously published results for all special cases of the IQHK potential across various diatomic molecular systems. Furthermore, we verify that our results are consistent with the canonical Heisenberg-Born-Jordan-Dirac commutation relations and Heisenberg’s uncertainty principle, thereby confirming the robustness and reliability of the proposed methodology within this framework.</p>
