The G-factor, or g-factor, is a dimensionless quantity that characterizes the magnetic moment and angular momentum of particles, such as electrons, protons, and neutrons. It is particularly significant in the context of atomic and particle physics, as well as in magnetic resonance and quantum mechanics. 1. **Electron g-factor**: For an electron, the g-factor is close to -2. This factor arises from the electron's intrinsic properties, specifically its charge and spin.
