Abstract
The fine-structure constant is traditionally treated as a fixed, universal constant that defines the strength of electromagnetic interaction. This work introduces the Abdeslam Atomic Motion Law (AAML), a structural model that defines the constant as a local ratio of electron velocity to atomic charge and light speed. In hydrogen-like atoms, AAML reproduces the classical value exactly. In multi-electron atoms, it incorporates effective nuclear charge to reflect electron shielding. This model produces fine-structure energy shifts that align more closely with experimental spectroscopic data than predictions using a fixed constant. The findings suggest that the fine-structure constant is not truly universal but emerges from internal atomic structure. The AAML framework invites re-examination of assumptions in quantum electrodynamics and offers a new structural foundation for atomic theory.
