Article CAS PubMed ADS Google Scholar WebThe proton radius is the distance from the proton’s center to the edge of the proton. In energy wave theory, the proton is modeled as a pentaquark (four particles and an antiparticle), allowing for the attractive and repelling forces used to calculate atomic orbital energies and distances in the Atomic Orbitals paper. This paper calculates ...
