Nuclear Spin-Orbit Coupling

Strong Spin–Orbit Coupling in Nuclear Physics In nuclear physics, strong spin–orbit coupling is the crucial interaction that makes the nuclear shell model work and explains the observed magic numbers. Below is a clear, step-by-step explanation of what it is, why it is...

Nuclear Magic Numbers

Magic Numbers in Nuclear Physics Magic numbers are one of the key organizing principles in nuclear physics. They explain why certain nuclei are exceptionally stable, much like noble gases in atomic chemistry. What Are Magic Numbers? In nuclear physics, a magic number...

Compton Wavelength

Compton Wavelength by Thomas Lee Abshier, ND 10/20/2025 The Compton wavelength is a fundamental physical constant associated with a particle, defined as the wavelength of a photon whose energy is equivalent to the rest energy of the particle. It represents a...

The Lagrangian

What is a Lagrangian? In physics, a Lagrangian is a mathematical function that describes the dynamics of a physical system. It is central to Lagrangian mechanics, one of the formulations of classical mechanics, and it also plays a key role in quantum mechanics,...
