Description 38 Application This document presents a geometric reinterpretation of electron interference grounded in the internal structure of the electron as formulated within the 0-Sphere research program. In contrast to the conventional point-particle description, the present framework models the electron as possessing a minimal internal geometry consisting of two energy kernels separated at the Compton scale. Energy circulates between these kernels through radiative exchange, generating an internal phase variable and naturally giving rise to a spinorial SU (2) structure with 4π periodicity. Within this configuration, interference phenomena are not treated as purely external wave-superposition effects. Instead, observable interference visibility emerges from a quartic internal energy identity governing the cyclic redistribution of energy between the two kernels: E0=E0cos4θ+sin4θ+1/2 sin2 (2θ). From this quartic structure, a central result follows: when internal phases are not externally controlled and ensemble averaging is performed over uniformly distributed internal phase values, the interference visibility is bounded by a universal limit ⟨V⟩ = √2−1 ≈ 0. 4142. This bound arises without adjustable parameters and represents an intrinsic visibility ceiling independent of environmental decoherence. The model therefore predicts a structural distinction between electron interference (quartic identity, intrinsic visibility limit) and photon interference (quadratic identity, no intrinsic visibility limit). A second principal result concerns the physical interpretation of Zitterbewegung. By applying relativistic kinematics and Lorentz contraction to the internal oscillatory motion, and using the experimentally measured anomalous magnetic moment as input, the framework derives a characteristic internal velocity vᵦb ≈ 0. 04047c. This value constitutes a falsifiable prediction. Failure to observe internal motion at this scale in sufficiently high-resolution experiments would impose direct constraints on the proposed internal geometric model. Conceptual Scope This work aims to: Derive electron interference visibility from internal geometric first principles Establish SU (2) spinorial structure from two-kernel internal configuration Demonstrate the quartic origin of intrinsic visibility reduction Connect internal oscillatory dynamics to relativistic constraints Provide explicit falsifiable predictions Relation to the 0-Sphere Research Program The present manuscript synthesizes and extends prior results in the 0-Sphere model series, including earlier work on anomalous magnetic moments, radiative energy transfer, Noetherian conservation reinterpretation, and geometric formulations of Zitterbewegung. Where earlier publications introduced the quartic identity and noted the visibility bound, the present work provides a unified derivation linking: two-kernel internal geometry quartic energy circulation SU (2) spinorial periodicity ensemble phase averaging experimentally constrained internal velocity Together, these elements form a coherent internal-geometric explanation of electron interference phenomena.
