The Cottingham formula expresses the leading contribution of the electromagnetic interaction to the proton-neutron mass difference as an integral over the
How does the mass of a nucleon differ with the mass of an electron? What is the difference between a subatomic particle and a subnuclear particle? How does the mass of a nucleon compare with the mass of an electron If the rest energies of a proton and a neutron (the two constituents ...
Moreover, with the mass difference between the proton and neutron approximated to zero, we note that the proton fraction x ≡ np/n can be solved from the equation $$\frac{\partial \epsilon (\bar{n},x)}{\partial x}+{\mu }_{e}(\bar{n},x)=0,$$ (8) where \({\mu }_...
massneutronsnumericalsperturbation theoryThe neutron-proton mass difference is re-evaluated on the basis of new experimental data and knowledge from high-energy electron scattering that the electromagnetic form factors of the proton can no longer be considered as identical. Calculations are performed ...
Protons, positively charged particles in an atom's nucleus, define an element's identity, while neutrons, neutral particles, contribute to atomic mass but not charge.
