Instant two-body equation in Breit frame.
A quasipotential formalism for elastic scattering from relativistic bound states is based on applying an instant constraint to both initial and final states in the Breit frame. This formalism is advantageous for the analysis of electromagnetic interactions because current conservation and four momentum conservation are realized within a three-dimensional formalism. [1] Wave functions are requir...
متن کاملMomentum Spectra in the Current Region of the Breit Frame in Deep Inelastic Scattering at HERA
The production of charged particles has been measured in deep inelastic scattering (DIS) with the ZEUS detector. The evolution of the moments of the scaled momenta distributions in Q 2 and x has been investigated in the current fragmentation region of the Breit frame. The results in the current region are compared to e + e − data and QCD analytical calculations. The results are consistent with ...
متن کاملBreit interaction in heavy atoms
In this letter we discuss how to include Breit interaction in calculations of low-energy properties of heavy atoms in accurate and effective way. In order to illustrate our approach we give some results for Cs and Tl. Introduction. It is well known that in high accuracy atomic calculations one may need to go beyond the Coulomb approximation for the two-electron interaction. The usual next step ...
متن کاملConstructing a Body-Fixed Reference Frame for a Polyatomic Molecule
An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
متن کاملHow to obtain a covariant Breit type equation from relativistic Constraint Theory
It is shown that, by an appropriate modification of the structure of the interaction potential, the Breit equation can be incorporated into a set of two compatible manifestly covariant wave equations, derived from the general rules of Constraint Theory. The complementary equation to the covariant Breit type equation determines the evolution law in the relative time variable. The interaction pot...
