On the Non-Relativistic Groundstate Energy of Positronium in Relativistic Schroedinger Theory
M. Mattes, M. Sorg
The \emph{Relativistic Schrödinger Theory} (RST) has been set up as an alternative form of particle theory. This theory obeys the fundamental symmetries which are required to hold…
Dimorphism of Ortho-Positronium in Relativistic Schrödinger Theory
M. Mattes, M. Sorg
The non-relativistic energy levels of ortho-positronium are calculated in the quadrupole and octupole approximations for the interaction potential. For this purpose, the RST eigenv…
Quadrupole Approximation for Para-Positronium in Relativistic Schrödinger Theory
M. Mattes, M. Sorg
The non-relativistic energy levels of para-positronium are calculated in the quadrupole approximation of the interaction potential. This approximation technique takes into account…
Spherically Symmetric Approximation (and beyond) in Relativistic Schroedinger Theory
M. Mattes, M. Sorg
The energy eigenvalue problem of non-relativistic positronium is considered within the framework of Relativistic Schroedinger Theory (RST), and the results are compared to those of…
Gauge-Invariant Energy Functional in Relativistic Schroedinger Theory
M. Mattes, M. Sorg
The non-invariant energy functional of the preceding paper is improved in order to obtain its gauge-invariant form by strictly taking into account the non-Abelian character of Rela…
Exchange Interactions and Principle of Minimal Energy in Relativistic Schroedinger Theory
M. Mattes, M. Sorg
The principle of minimal energy, which has been set up in the preceding papers for systems of non-identical particles (e.g. positronium), is now generalized to include also identic…
