interactions, which appears in all equations of microscopic electrodynamics. The elementary charge is exactly equal to the electric charge of the electron, proton, and nearly all other charged elementary particles, which by virtue of this fact are the material carriers of the smallest charge in ...
We performed a parabolic fit of the quantum well state dispersion measured by ARPES to extract the electron effective mass. From the fits we found that, starting from high binding energy, the masses of the sub bands 1–4 are equal to m1 = 1.0m0, m2 = 1.0m0, m3 = 0.8m0...
We study the behaviour of the neutron-proton mass difference in the nuclear medium. The main contribution to this quantity from charge symmetry breaking in the meson sector is given by ρω mixing. In order to include this effect in the QCD sum rules, we extend the sum rules to finite ...

Effects of the neutron spin-orbit density on the nuclear charge density in relativistic models - art. no. 054303 The neutron spin-orbit density contributes to the nuclear charge density as a relativistic effect. The contribution is enhanced by the effective mass stemm... H Kurasawa,T Suzuki -...
atom. There is one atom that has only a single proton and no neutrons: hydrogen. As a neutron has no actual electrical charge, the only charge of hydrogen is supplied by the single proton. Because of this association, the term proton is sometimes used synonymously with the term hydrogen ...
