Current data from the Stanford Linear Accelerator Center and from CERN on the structure function combinations F p 2− F n 2, F n 2/ F p 2 and σ L σ T are in line with both the Stockholm diquark model and perturbative QCD, considering the low statistics as well as the possibility...
We have a new kind of particle to add to the electron, the proton, and the neutron. That new particle is called a photon. The new view of the interaction of electrons and photons that is electromagnetic theory, but with everything quantum-mechanically correct, is called quantum ...
Proton and neutron polarization differences in the reactionsH3(p→,p)H3andHe3(n→,n)He3 The reactions 3H(p,p)3H and 3He(n,n)3He are analyzed within the framework of the dynamical R-matrix methodology. When compared at equal incident energies, measurements indicate that forward angle 3H(...
The reason this unit was chosen is historical, and we shall not go into it now. More massive particles are put higher up on the chart; we see that a neutron and a proton have almost the same mass. In vertical columns we have put the particles with the same electrical charge, all ...

Elements are ordered in the periodic table by their: A) atomic number or proton and neutron number. B) atomic number or electron number. C) atomic number or proton number. D) atomic weight or electron and neutron number. E) atomic mass or electron an ...
Protons and neutrons are made up of smaller subatomic particles. Whenprotonsor neutrons get close enough to each other, they exchange particles (mesons), binding them together. Once they are bound, it takes considerable energy to break them apart. To add protons or neutrons, the nucleons either...
It is found that the simple model reproduces the interaction with about 30% accuracy. It also indicates that a larger interaction constant should be used when the proton and neutron are in the same single-particle state than when they are in different states. 展开 关键词:...
A method for determining the isospin term of the optical potential by comparison of the optical potentials found from analyses of neutron and proton scattering by the same nucleus at the same energy was presented. Calculations were made using previous data for 14.5-Mev neutrons and data obtained ...
