The spins of electrons and protons are considered to be connected with their moments of quantity of motion. But since this conception contradicts the prohibition against faster-than-light velocities, spin is therefore considered to be just a quantum-mechanical value. So, we know that there exists...
spin, in physics, the amount of angular momentum associated with a subatomic particle or nucleus and measured in multiples of a unit called the Dirac h, or h-bar (ℏ), equal to the Planck constant divided by 2π. For electrons, neutrons, and protons, the multiple is 0.5; pions have ...

Spin dynamics for electrons is very different from that for protons. The main cause of the difference lies in synchrotron radiation. Synchrotron radiation is such an overwhelming mechanism for electrons while negligible for protons that these two areas of spin dynamics evolved along entirely different ...
The indirect spin–spin coupling (also known as scalar or J-coupling) is an interaction between nuclear moments mediated by electrons participating in chemical bonds between the nuclei. From: Comprehensive Biomaterials, 2011 About this pageSet alert ...
Protons and electrons have an extrinsic angular momentum and an intrinsic angular momentum. This extrinsic angular momentum comes from the movement of an electron around a nucleus. The intrinsic angular momentum is called electron spin, and it describes the direction that which an electron rotates ...

Pauli exclusion principle, assertion that no two electrons in an atom can be at the same time in the same state or configuration, proposed (1925) by the Austrian physicist Wolfgang Pauli to account for the observed patterns of light emission from atoms.

The topics covered in the conference ranged from the physics that can be done with polarized beams of particles (protons, electrons, gamma-rays, etc.) to the techniques and instrumentation necessary to achieve this. Topics included: nucleon structure measurements (from where does the spin of the...
