Binding energy corrections in positronium decays
Positronium annihilation amplitudes that are computed by assuming a factorization approximation with on-shell intermediate leptons, do not exhibit good analytical behavior. We propose an ansatz which allows to include binding energy corrections and obtain the correct analytical and gauge invariance behavior of these QED amplitudes. As a consequence of these non-perturbative corrections, the par...
متن کاملAtomic and molecular structures of positronium, dipositronium and positronium hydride
The three positron based chemical entities, analogous to hydrogen atom, hydrogen molecule and hydride, are drawing increasing attention in the literature. While a lot is known about the binding energies, not much is known about the radii of the atoms and ions and bond lengths and structures of these exotic entities. This article brings for the first time exact values of these structural propert...
متن کاملRelativistic and QED energy shifts in positronium ion
The leading relativistic and QED corrections to the ground state energy of the three-body system e − e + e − are calculated numerically using a Hylleraas correlated basis set. The accuracy of the nonrelativistic variational ground state wave function is discussed with respect to the convergence properties at the increase of the basis dimension and to the variance of the energy expectation value...
متن کاملBinding energy of the positronium negative ion: Relativistic and QED energy shifts
The leading relativistic and QED corrections to the ground-state energy of the three-body system e−e+e− are calculated numerically using a Hylleraas correlated basis set. The accuracy of the nonrelativistic variational ground state is discussed with respect to the convergence of the energy with increasing size of the basis set, and also with respect to the variance of the Hamiltonian. The corre...
متن کاملThe Ground State Energy of Heavy Atoms: Relativistic Lowering of the Leading Energy Correction
Abstract. We describe atoms by a pseudo-relativistic model that has its origin in the work of Chandrasekhar. We prove that the leading energy correction for heavy atoms, the Scott correction, exists. It turns out to be lower than in the non-relativistic description of atoms. Our proof is valid up to and including the critical coupling constant. It is based on a renormalization of the energy who...
