How to Deduce Masses and further Parameters of Particles and Nuclei

Quantities of free particles and masses of nuclei are deduced from a geometry of gravitation and electromagnetism as found for the first time by Rainich. The theory is nothing else than General Relativity completed with a "simple idea" as foreseen by Wheeler. This "simple idea" leads to far reaching consequences and solves problems of General Relativity. In addition, the omnipresent quantization is revealed to be a necessary consequence of the geometric theory. At this place, quantities of particles and masses of nuclei are depicted by means of numerical simulations according to geometric equations. The algorithm is explained. The computations are repeatable by everyone. The results correlate significantly with the values from experiment.
