A complete analysis of this phenomenon may shed light on the Pauli problem, namely, why $α$ = 1/137.7 pages, Tex; to appear in the Proceedings of the Conference on Quantum Aspects of Beam Physics, held at Monterey, California in January 1998High Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
