Electrically bound quantum particles and Pure Bound Field Theory: precise physics of simple atoms and new bound state of the proton and electron

Abstract

We present basic ideas of Pure Bound Field Theory (PBFT) we developed earlier (A. L. Kholmetskii et al. Eur. Phys. J. Plus, 126 (2011) 33; Eur. Phys. J. Plus, 126 (2011) 35)), which explicitly takes into account the non-radiating nature of electromagfnetic field of quantum bound partictes, and which allows eliminating the available subtle deviations between experimental and theoretical data in precise physics of simple atoms. We show that the specific corrections of PBFT, being introduced into the basic equations of atomic physics, allow two different solutions for stationary energy states for electrically bound system "proton plus electron". One of them corresponds to the usual hydrogen atom, whereas another stationary state is characterized by the radius of stationary orbit about 5 fm and the binding energy about -0.511 Mev.
